ABSTRACT:
A push-to-connect, pull-to-disconnect ball detent coupling operable with one hand has a socket, a plug, detent balls carried by the socket for holding the plug in coaxial coupled relation, and spring-biased sleeves on the socket and on the plug. The socket sleeve spring is located in an annular passageway between the sleeve and the socket on the side of the detent balls opposite the coupling end of the socket. The plug sleeve spring is located in an annular passageway between the sleeve and the plug on the side of the detent retaining means opposite the coupling end of the plug. During coupling movement, the outer terminal end of the plug sleeve engages the outer terminal end of the socket sleeve to move the socket sleeve to actuate the detent balls. To release the plug from the socket, an operator pushes either the socket sleeve or the plug sleeve against the plug sleeve spring so that an annular groove on the inner surface of the socket sleeve comes into registry with the ball retaining apertures thereby releasing the balls from the annular groove in the plug. The coupling is compact and suitable for use in the areas of limited access.
