Abstract: There is disclosed in the present application a locking joint for securing together a male and a female member, illustrated in the present application being employed for securing together the parts of a socket wrench assembly including the sockets themselves as well as such auxiliary equipment as extensions and ratchet drives. In each joint, there is incorporated in the male member a lock in the form of a spring-pressed member mounted for sliding motion at an acute angle to the axis of the joint and having its outward end chisel-shaped to provide a tooth which engages the interior of the female member with a wedging action.

Abstract: There is disclosed in the present application, a retainer for sockets especially useful in connection with socket wrenches and accessories. The retainer, which is added to a male member includes a spring-pressed lever which is depressed as the mating female member or socket is introduced over the lever and then locks into the interior of the socket with a self-energizing form of engagement to resist withdrawal until the spring pressure is overcome to release the lock.
