ELECTRIC COUPLER

An elecric coupler (1) is mounted on an end of an armoured electric cable (6) having a plurality of individually screened conductors (5). The coupler comprises a metal head (2) which forms the front face of the coupler; at least two tubes (3) of electrically insulating material secured in the head; an electrical contact (4) positions within each tube and electrically connected to a respective conductor of the cable from an end part of which the screen (14) has been cut back, clamping means (10) electrically and mechanically connected to the head, clamping the wire armouring (9) of the cable; a foramenous metallic earth screen (16) surrounding the tubes and the said end part of each conductor; and a hard resinous insulating compound (19) which fills the voids within the screen, embeds the screen and forms the outer circumferential surface of the coupler.
