"RELEASABLE PUSH-TO CONNECT TUBE FITTING" ABSTRACT OF THE DISCLOSURE A releasable push-to-connect tube fitting wherein a collet receiving the tube end is provided with longitudinally extending inner slots sized so as to limit constriction of the collet to maintain the outer diameter of the inner end of the collet greater than the minimum diameter of a confronting camming surface of a fitting body member for effectively positively retaining the collet in the body member upon assembly of the fitting elements. The collet includes an enlarged outer end exposed exteriorly of the fitting body for use in releasing the tube from the fitting when desired. The collet is retained in the body by constric- tive deformation of the body outer end portion after installation of the collet therein. The constrictive deformation is effected by a suitable tool. In one embodiment, the fitting body is adapted to be secured in a port element. An eyelet may be provided for reception within the tube end to be connected to the fitting. The collet may be selectively provided with a plurality of tube biting teeth or a helical tooth.
