PCT No. PCT/GB79/00213 Sec. 371 Date Aug. 20, 1980 Sec. 102(e) Date Aug. 15, 1980 PCT Filed Dec. 18, 1979 PCT Pub. No. WO80/01339 PCT Pub. Date Jun. 26, 1980.An electrical coupling device, for example a 3-pin plug, of the kind comprising a housing, for example a plug base (2), means, such as conductor-piercing members (20-22), within the housing for effecting electrical connection to one or more conductors (not shown) of an electrical cable (1) which enters the housing in use of the device and a cable grip for clamping the cable relative to the housing. The cable grip comprises a pair of cooperating jaws (8, 9) adapted to receive the cable (1) therebetween and camming means formed in the housing into which the pair of jaws with the cable therebetween can be pressed. In the embodiment illustrated, the camming means is provided by the opposed walls (18, 19) of a recess (7) in the base (2), which walls are arranged to exert pressure on a pair of opposed surfaces (11a, 12a) of the pair of jaws (8, 9) to force the jaws towards one another to grip the cable when the jaws are pressed into the recess in a direction substantially perpendicular to the path of the cable through the jaws. The base (2) comprises means, for example the end wall (17) of the recess (7), to limit movement of the jaws in the direction of the path of the cable through the jaws when a tensile force is applied to the gripped cable in a direction tending to pull the cable out of the coupling device.
