Abstract: The connector comprises a tubular generally cylindrical connector body having means for retaining an armored BX electrical cable, or any other desired cable, therein. An internally threaded nut is mounted on an externally threaded front portion of the body. The rear portion of the body is provided with a plurality of resiliently yieldable latching arms which slant outwardly and forwardly therefrom. The latching arms yield inwardly when the connector body is pushed rearwardly through an opening in a supporting wall, whereupon the latching arms spring outwardly behind the supporting wall. The nut can then be tightened so that the wall will be clamped between the nut and the latching arms. In this way, the connector can be mounted on a supporting wall which is inaccessible from the rear side.
