ABSTRACT:
A snap-fastenable coupling for a fluid duct, in particular for a motor vehicle, the coupling comprising a cylindrical bushing secured to one end of a duct for coupling to a tubular endpiece which is designed to be inserted into the bushing and which has a peripheral projection in the vicinity of its free end, and a cylindrical locking member fitted around the bushing and designed to co-operate with a portion of the bushing and with the peripheral projection on the endpiece to hold the endpiece engaged in the bushing, wherein the locking member has at least one longitudinal slot and is formed with two side tabs organized on respective opposite sides of said slot to enable the locking member to be opened for disconnection of the duct from the endpiece by applying thrust in two opposite directions on the tabs. The invention applies in particular to circuits for fluids under relatively high pressure in motor vehicles.
