A releasable quick-connect coupling comprises tubular nipple and socket parts. The nipple is formed by a metal tube and a sleeve on the outer periphery of the tube, the sleeve being retained by beads formed on the tube. A locking ring is mounted in an annular groove formed in the sleeve. The socket includes a tubular adapter and a nut threaded on one end of the adapter. An annular lock groove is formed between the nut and the adjacent end of the adapter, and the groove receives the outer periphery of the locking ring when the parts are assembled. A seal is provided between the adapter and the tube. To disassemble the coupling, the nut is first partially unthreaded from the adapter to release the seal and thereby equalize the pressure. Then the nut is completely unthreaded, thereby releasing the locking ring and the nipple. The locking ring may be removed from the sleeve so that the nut may be removed from the nipple.
