ABSTRACT:
A connector has a coupling ring received about a plug shell, the inner wall surfaces of the coupling ring having a coded arrangement of keyways to insure proper mating with similar coded keys on a proper receptacle. An opening in the coupling ring slidingly receives a metal ball. A notch is formed in a surface of a detent spring arranged such that when the plug shell and receptacle shell are fully mated, the ball is aligned with and can move into a notch in the detent spring. A retainer ring located over the coupling ring lies immediately opposite the opening containing the metal ball. The inner surface of the retainer ring has a groove which on receiving the ball leaves no obstructing part of the ball extending inwardly of the coupling ring. Rotation of the retainer ring can locate either the groove opposite to the metal ball opening or a smaller diameter surface which will cause the ball to lock the connector parts.
