Abstract
The disclosures relates to a tube coupling (10) for a tube (11) having a body (12) with open ended throughway (13) to receive the tube and a collet (21) in the open end of the throughway having resilient arms (23) engaging a tapered cam surface (20) in the body to clamp the ends of the arms against a tube extending through the collet into the body to lock a tube in the body. The body has a cylindrical outer surface and a cylindrical cover (30) encircles and is slidable along the body. One end of the cover has an end wall (32) extending across the end of the body opposite the open end of the throughway with an aperture (33) through which the tube extends. The other end of the cover has an internal annular projection (35) which snaps over the end of the cylindrical body to retain the cover on the body while permitting the cover to slide linearly along the body. The end wall of the cover is engagable with the collet where it projects from the open end of the throughway and by pressing the end wall of the cover towards the end of the coupling body, the collet is depressed into the body to hold the resilient arms away from the tapered cam surface in the coupling body and permit the tube (11) to be withdrawn. The arrangement is particularly useful for relatively small couplings utilized in confined spaces where manual depression of the projecting part of the collet from the end of the coupling body would be difficult.
