Abstract
Abstract A security clip which is particularly adapted for securing a tape strip in a closed loop form has a pair of hinge connected arms normally disposed in an open, diverging attitude. One of the arms is adapted to be fastened to the end of a tape strip and carries means for engaging and securing a reach of the tape strip fed between the arms to clamp the strip in a closed loop configuration when the arms are closed. The arms carry cooperating cutting elements which sever the tape strip when the arms are closed to facilitate removal of the length of a strip excess to that required to form a closed loop of a desired size. The arms also carry cooperating latching elements which lock the clip when the arms are closed and render the clip substantially tamperproof under normal conditions of usage.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
238 words
A security clip comprising a first arm adapted to be fastened to a tape strip adjacent one end thereof and transverse the longitudinal axis of the strip, and a second arm hinged to said first arm and normally in open, diverging relationship with respect to said first arm, means carried by at least one of said arms for gripping portions of the tape strip when the strip is looped on itself and fed between said arms and said arms are closed by pivoting said second arm toward said first arm about said hinge, cooperating latching means carried by said arms for retaining said arms in a closed condition on the reach of the strip loop fed therethrough, and cooperating cutting means carried by said arms operable to sever the strip during closing of said arms and thereby facilitate removal of portions of the tape strip excess to the length thereof necessary to form a closed loop of a desired size, said last mentioned means including a platen joined to a marginal edge of said first arm through a reversely bent bite and spacedly overlying the internal surface of said first arm, said platen having a relatively narrow slot formed therein and extending generally parallel to said bite, and a knife blade depending from a marginal edge of said second arm and oriented to register with said slot in said platen and pass therethrough when said arms are closed.
Claim 2
Dependent Claim
238 words
A security clip comprising a first arm adapted to be fastened to a tape strip adjacent one end thereof and transverse the longitudinal axis of the strip, and a second arm hinged to said first arm and normally in open, diverging relationship with respect to said first arm, means carried by at least one of said arms for gripping portions of the tape strip when the strip is looped on itself and fed between said arms and said arms are closed by pivoting said second arm toward said first arm about said hinge, cooperating latching means carried by said arms for retaining said arms in a closed condition on the reach of the strip loop fed therethrough, and cooperating cutting means carried by said arms operable to sever the strip during closing of said arms and thereby facilitate removal of portions of the tape strip excess to the length thereof necessary to form a closed loop of a desired size, said last mentioned means including a platen joined to a marginal edge of said first arm through a reversely bent bite and spacedly overlying the internal surface of said first arm, said platen having a relatively narrow slot formed therein and extending generally parallel to said bite, and a knife blade depending from a marginal edge of said second arm and oriented to register with said slot in said platen and pass therethrough when said arms are closed.
Claim 3
Dependent Claim
48 words
A security clip according to claim 1 wherein said platen has more than one slot formed therein and said second arm has more than one knife blade depending therefrom, each of said knife blades being oriented to register with one of said slots when said arms are closed.
Claim 4
Dependent Claim
83 words
A security clip according to claim 1 wherein said means carried by one of said arms for gripping the tape strip comprises a resilient, compressible pad fixed to the internal surface of said first arm and projecting therefrom toward said second arm, said pad carrying adhesive on its external surfaces, which adhesive is adapted to adhere to the reach of the tape strip which is fed between said arms and clamped against said pad by said second arm when said arms are closed.
Claim 5
Dependent Claim
103 words
A security clip according to claim 1 wherein the end of said second arm remote from said hinge has a resilient hook depending therefrom and the corresponding end of said first arm has a hook receiving opening formed therein, whereby said hook is adapted to snap into said opening when said arms are closed and seat behind and grip an edge of said first arm defining said slot, said hook and the said edge of said slot constituting said cooperating latching means carried by said arms for retaining said arms in a closed condition on the reach of the strip loop fed therebetween.
Claim 6
Dependent Claim
36 words
A security clip according to claim 1 wherein said first arm has a generally centralized opening formed in the base thereof for the receipt of a fastener element for securing said arm to a tape strip.
Claim 7
Dependent Claim
229 words
A security clip comprising a first arm adapted to be fastened to a tape strip adjacent one end thereof and transverse the longitudinal axis of the strip, said first arm having a generally centralized opening formed therein for the receipt of a fastener element for securing said arm to the strip and having a plurality of barbs struck outwardly therefrom adjacent the periphery of said opening, said barbs being adapted to bitingly grip the strip end fastened to said arm to maintain said clip in proper transverse orientation relative to the longitudinal axis of the strip, and a second arm hinged to said first arm and normally in open, diverging relationship with respect to said first arm, means carried by at least one of said arms for gripping portions of the tape strip when the strip is looped on itself and fed between said arms and said arms are closed by pivoting said second arm toward said first arm about said hinge, cooperating latching means carried by said arms for retaining said arms in a closed condition on the reach of the strip loop fed therethrough, and cooperating cutting means carried by said arms operable to sever the strip during closing of said arms and thereby facilitate removal of portions of the tape strip excess to the length thereof necessary to form a closed loop of a desired size.
Claim 8
Dependent Claim
229 words
A security clip comprising a first arm adapted to be fastened to a tape strip adjacent one end thereof and transverse the longitudinal axis of the strip, said first arm having a generally centralized opening formed therein for the receipt of a fastener element for securing said arm to the strip and having a plurality of barbs struck outwardly therefrom adjacent the periphery of said opening, said barbs being adapted to bitingly grip the strip end fastened to said arm to maintain said clip in proper transverse orientation relative to the longitudinal axis of the strip, and a second arm hinged to said first arm and normally in open, diverging relationship with respect to said first arm, means carried by at least one of said arms for gripping portions of the tape strip when the strip is looped on itself and fed between said arms and said arms are closed by pivoting said second arm toward said first arm about said hinge, cooperating latching means carried by said arms for retaining said arms in a closed condition on the reach of the strip loop fed therethrough, and cooperating cutting means carried by said arms operable to sever the strip during closing of said arms and thereby facilitate removal of portions of the tape strip excess to the length thereof necessary to form a closed loop of a desired size.
