Abstract

There is provided a connector for connecting non-metallic sheathed cable to an electrical box, with such connector including a substantially tubular body defining an axially extending passageway for receiving one or more cables to be connected. The tubular body has a proximal edge and a distal edge. The connector further includes a first end adjacent the distal edge of the tubular body for insertion into an opening in the electricl box, with the first end having an outwardly extending abutment rib circumscribing at least a portion of the exterior periphery of that end and spaced from the distal edge. The first end further includes at least one releasable locking device having an actuator tab to provide for release of the first end from the opening as desired. A second end of the connector is provided adjacent the proximal edge includes at least one adjustable clamping member which operates independently of the locking device, and which is adapted to substantially immovably clamp the cable within the connector. In a preferred embodiment, the connector of the present invention includes a pair of oppositely disposed locking devices, and a pair of opposed adjustable clamping members. The adjustable clamping members may be provided as wedge-shaped levers which are selectively extending into the connector to bind the cable as a result of rotation of a locking collar threadedly telescoped over the second end of the connector.
