Abstract: A connector assembly has two rotatable parts both of which have external splines. An internally-splined locking ring is slidable along the assembly into a locking position where the splines on the ring engage the splines on both the rotatable parts so that relative rotation of the parts is prevented.

Abstract: A coupling for one end of screened conduit has two brass cones which are nested together and through which extend screened cables. Several apertures are formed around the inner cone which open into the space between the two cones. The braiding of each cable is stripped to one side and threaded through individual apertures so that it extends into the space between the cones. A threaded clamping nut urges the two cones together so that the braiding is clamped between them and good electrical connection is made.

Abstract: A device (1) comprising a flexible and resilient sleeve (2) made of rubber, rubber-like, plastics or similar material and a metal end termination (3) which has a screw thread connection with an electrical component (4) in the form of a multi-pin connector or plug. The end termination (3) has an interface (5) for conductors or wires of the multi-core cable and a body (6) which has a tapered entry (7) in which is received the sleeve (2) and metal braids (8) which screen the cable (9). There is a seal in the form of an O-ring (10) at the blind end of the entry (7) to prevent moisture getting into the cable. The other end of the sleeve (2) from the body (6) is mechanically secured as by adhesive to the other surface of an outer sheath of the multi-core cable (9) at anchor (11). To re-enter connection, the termination (3) and component (4) are unscrewed and pulled apart in direction (x) so that the convulsions of the sleeve (2) bunch up.
