<p>PROBLEM TO BE SOLVED: To prevent connection between a plug and a socket of a hose connector from coming off easily. SOLUTION: A release ring 30 having a protruding part 31 at the end face, and a stopper ring 20 having recessed parts 24 at the end face so as to be fitted to the rotruding part 31, are fitted to the periphery of a socket body 10 having a lock ball fitted with play to a peripheral wall 11 and also having plug fit-in space A at the inner surface. The release ring 30 is fitted into the groove 13 through reversely bent claws 37 so as to be slidable only in an axial direction. The stopper ring 20 is click-engaged with the socket body 10 through the protruding part 22 on the inner surface. After connecting a plug to the socket body 10, the stopper ring 20 is rotated, and the recessed parts 24 are stopped in positions not corresponding to the protruding part 31 of the release ring 30, thus impeding sliding of the release ring 30 from a lock ball pressing position.</p> |
