Tube-to-hose connection

Claim 2

A hose and tube connection comprising: a tube, a clamp member having an annular portion, a plurality of fingers extending axially from said annular portion and about said tube, said fingers being inherently resiliently biased toward open positions, retaining means formed in said clamp member and said tube being mutually engageable to locate said clamp member about said tube at a predetermined axial position of said tube, said clamp member retaining means being resiliently displaceable to permit positioning of said clamp member relative to said tube, a hose being flexible relative to said tube having an end portion receivable within said clamp fingers and about said tube, a sleeve positioned about said clamp member, said sleeve being slidable in one axial direction relative to said clamp member to constrict said fingers about said hose and to compress said hose between the clamp member and the tube, said sleeve being slidable in the other axial direction to release said fingers and said hose.

Claim 3

A hose and tube connection according to claim 1 and wedge portions forming the end portions of said fingers, said sleeve having an opening engagable with said wedge portions and axially movable relative thereto to constrict or release said fingers about said hose.

Claim 4

A hose and tube connection according to claim 1 and a portion of said clamp member forming an abutment means to determine the maximum extent of axial insertion of said hose within the fingers and about the tube.

Claim 5

A hose and tube connection according to claim 1 and lock means formed in said clamp member comprising abutments having ramp sides and sides substantially normal to the axis of the annular portion, said substantially normal sides being engageable with said sleeve to slidably lock the sleeve in a constricting position about the clamp member fingers, said lock means comprising a plurality of arms extending axially opposite said fingers, the end portions of said arms being radially spaced from said tube, said arms being radially deformable to release and permit axial movement of said sleeve thereby relieving the constriction of the clamp member fingers.

Claim 6

A hose and tube connection comprising: a tube, a clamp member having a plurality of fingers extending axially about said tube, a bead formed on said tube axially spaced from its end, a recess formed in aid clamp member, said bead being receivable within said recess to locate and retain said clamp member in a fixed axial position on said tube, said fingers forming an axially opening cage adjacent the end of said tube, a hose having an end insertable and receivable within said cage, abutment means formed within said cage to determine the maximum extent of axial insertion of said hose into said clamp member and about said tube, said fingers including wedge portions adjacent the cage opening, a sleeve received about said clamp member being axially movable relative thereto, a portion of said sleeve member being engageable with said wedge portions to deform said fingers and coRrespondingly constrict the cage opening as the sleeve member is axially advanced along the clamp member, lock means formed in said clamp member engagable with said sleeve to lock the sleeve in a constricting position about the clamp member fingers, said lock means comprising a pair of arms extending axially opposite said fingers, the end portions of said pair of arms being radially spaced from said tube, said pair of arms being radially deformable to release and permit axial movement of said sleeve thereby relieving the constriction of the cage opening.

Claim 7

A hose and tube connection comprising: a tube, a clamp member having a plurality of fingers extending axially about said tube, a bead formed on said tube axially spaced from its end, a recess formed in aid clamp member, said bead being receivable within said recess to locate and retain said clamp member in a fixed axial position on said tube, said fingers forming an axially opening cage adjacent the end of said tube, a hose having an end insertable and receivable within said cage, abutment means formed within said cage to determine the maximum extent of axial insertion of said hose into said clamp member and about said tube, said fingers including wedge portions adjacent the cage opening, a sleeve received about said clamp member being axially movable relative thereto, a portion of said sleeve member being engageable with said wedge portions to deform said fingers and coRrespondingly constrict the cage opening as the sleeve member is axially advanced along the clamp member, lock means formed in said clamp member engagable with said sleeve to lock the sleeve in a constricting position about the clamp member fingers, said lock means comprising a pair of arms extending axially opposite said fingers, the end portions of said pair of arms being radially spaced from said tube, said pair of arms being radially deformable to release and permit axial movement of said sleeve thereby relieving the constriction of the cage opening.

Claim 8

A hose and tube connection according to claim 5 and a plurality of radially inwardly extending teeth formed on said fingers engagable with said hose, an enlarged head formed on said head, said teeth being located adjacent said enlarged head and to the side thereof away from the end of the tube when the connection is in a locked, assembled relationship.
