Claim 1
Independent Claim
267 words
A utility device for securing sheet-like material to an associated structure comprising: a closed continuous ring-like element having a flexible ring means for encircling and attaching said device to an associated structure; a socket closure means carried on a first end of said ring means having an interior opening defined by a socket exterior side wall and back wall; a plug closure means carried on a second end of said ring means fitting within said socket closure means; said ring means being constructed from a resilient material facilitating flexing of said ring means to an open position wherein said socket and plug closure means are pulled apart accommodating placement of said ring means over said associated structure; said ring means flexing to a closed position in which said plug closure means is inserted in said socket closure means; rim means extending about said socket opening periphery for catching said sheet-like material; a material containing space defined by said peripheral side wall and back wall of said socket closure means, said rim means, and said plug closure means when inserted in said socket closure means in which said sheet-like material is gathered; said plug closure means including a rounded plug body generally devoid of sharp edges having an enlarged blunt surface for pushing and packing said material into said material containing space beyond said rim means; and said flexible ring means urging said plug and socket closure members together in said closed position and said gathered material being gripped between said rim means and plug body thereby securing said material, socket closure means, and plug closure means together.
