This disclosure relates to a releasable quick-connect fitting, comprising an insert having an annular lock groove and an annular release groove in the outer periphery thereof, the release groove having a smaller diameter than the lock groove. A receptacle has a bore for receiving the insert and an annular bore groove is formed in the bore. An annular retainer is mounted in one of the lock and release grooves and movable to the other of the grooves. The insert is movable to a lock position in the receptacle wherein the lock and bore grooves are substantially in radial alignment and the retainer extends into said lock and bore grooves, and movable to a release position in the receptacle wherein the release and bore grooves are substantially in radial alignment and the retainer extends into the release groove. A stop is removably connected to one of the insert and receptacle and engageable with the other, the stop preventing movement of the insert to the release position but enabling movement to the release position when removed.
