Patent ID: 7850208

Claim:
A stamped collet for a push-to-connect tube coupling, the collet being stamped from a metal sheet and formed into a generally cylindrical configuration, the collet having an annular base portion from which flexible tines extend forward from the base portion, the flexible tines being circumferentially arranged around a center axis of the collet and including inwardly inclined distal finger portions terminating at a biting edge for biting into a tube that has been inserted into the collet, wherein at least one of the flexible tines has an abutment portion connected to at least one side thereof for movement therewith, the abutment portion being generally perpendicular to the center axis of the collet and disposed forward of the biting edge of the respective tine, and wherein the abutment has a radially inner edge configured to engage the outer surface of the tube and configured to operate to resist inward movement of the inclined finger portion to prevent the biting edge from biting through the tube while also providing additional gripping force on the tube at a location forward of the biting edge.
