An electrical connector having a tubular support through which a power cable extends, and a contact housing within which the cable is connected to male or female contacts. The support and housing have mating quick threads facilitating their assembly after connection of the cable to the contacts. A lock means on the support automatically responds to connection of the support and housing to each other, to prevent their accidental separation. Normal operation of a cable clamping device on the support clamps and strain-relieves the cable within the support. Deformation of the cable to offer strain relief acts upon the lock means to prevent its movement from the position in which it locks the housing and support against accidental separation. A cable-clamping and strain-relieving device is disclosed, including a screw threadable laterally through an opening of a wiring device body into a power cable-receiving passage formed in the body. A swiveled head on the screw bears against the insulation of the conductor. Through the provision of guide slots in the body in which the screw is mounted, the head is maintained against rotation during advancement of the screw and removal of the screw from the body is prevented.
