A simple and inexpensive mineral insulated cable termination comprises a flexible plastics tube which at one end fits over the cut-back sheath of the cable and which at the other end is closed by an end wall spaced from the surface of the cable, each cable conductor passing through one of a plurality of throughbores in the end wall and, filling the space within the tube, waterproof electrically insulating compound. At a first position around the circumferential wall of the tube, the wall is slit throughout its length and radial thickness and at one position or at each of two positions circumferentially spaced from said first position the wall is adapted to constitute a hinge extending throughout the length of the wall. The abutting longitudinally extending parts of the wall at said first position are so shaped one effects a snap-fit with the other throughout the length of the tube.

Termination of mineral insulated electric cable

The rubber sealing cap of a mineral insulated cable termination has embedded in the circumferential wall of the cap effecting a circumferentially continuous, fluid-tight fit around the cut-back sheath of the cable, a resilient metal sleeve which protrudes from the end face of the tube and which has at its free end an inwardly extending flange which mechanically engages with the cable sheath and which is so inclined with respect to the cable sheath as to restrain the cap against removal from the cable. The protruding flange preferably has at its free end a plurality of circumferentially spaced teeth which engage with the cable sheath.
