ABSTRACT:
An electrical cable gland is provided which can be effectively clamped to metal strip types of armouring of an armoured electrical cable to effectively resist tension applied to such cable. The electrical cable gland includes at least two, and preferably three gripping dogs movable inwardly towards each other to effectively grip such metal strip armouring preferably between the dogs and on inner supporting sleeve forming part of the gland. Movement of the dogs can be by co-operating tapered surfaces on the dogs and body of the gland with the surfaces being axially movable relative to each other or by radially extending screw threaded fasteners passing through the wall of the body. An inwardly deformable, electrically conductive contact ring can be included, where required for making electrical contact with a lead or other conductive sheath.
