ABSTRACT:
A hose coupling has a tubular body (10) one end of which is intended to be attached to the end of a hose-pipe (14), and the other end of which has a bore (12) to receive the spigot (20) of a co-operating coupling (22) which is retained in the bore with a snap action. Three locking members (38) project into the bore (12) to hold the spigot (20) therein, and a locking sleeve (24) can be moved axially of the body (10) to force the locking members (38) to a release position, enabling the spigot (20) to be withdrawn from the bore to separate the couplings. The locking members (38) are interconnected by a ring (26) attached to the end of the body (10), and during assembly of the coupling the body (10) and the ring (26) interengage with a snap action to retain the ring (26) in fixed relationship to the body (10) and to hold the sleeve (24 ) captive on the body (10).
