Abstract: An electrical connector and cable termination system has a plug body (12) for mating with an opposed connector part, and an outlet body (22) to which a cable (60) is attached. The cable approaches the connector at an angle of 90.degree. to the major mating axis (C) of the connector. The outlet body and the plug body can be relatively rotated about the major axis of the connector. To this end, there is a retention ring (40) for inhibiting relative axial movement of the outlet body and the first connector body part, a key (50) and detent (54) for permitting relative rotation by at least 180.degree. but inhibiting relative rotation in excess of 360.degree., and an O-ring (34) of conductive resilient material between the outlet body and the plug body and for providing a limited degree of frictional resistance to the relative rotation of the outlet body and the first connector body part.
