Abstract: A cable seal insert for sealing a cable entry in a closure, including:(a) at least two plates, each of which, at least in use, has extending therethrough at least one aperture for a cable; and(b) sealing material located between the plates;wherein a peripheral surface of the seal insert which is substantially parallel to the or each cable aperture is substantially planar, and at least one of the plates is formed from non-elastomeric material.

Abstract: An assembly for protecting and insulating a junction such as a splice between cables. The assembly may be repaired or modified without a complete renewal of the junction. The assembly includes a relatively rigid longitudinally split tube which is positioned about the junction. Relatively rigid support means, such as rings, are positioned at the ends of the tube and a plurality of relatively flexible prongs project longitudinally, at spaced intervals, around the circumference of at least one end of the tube. The prongs may be attached to, or formed integrally with the support means. A heat-shrinkable sleeve of length greater than the length of the tube, with the support means and prongs, is disposed about the tube, support means and prongs. At least part of the inner wall of the heat-shrinkable sleeve is provided with a sealant so that on shrinking, the end regions of the sleeve overlying the free ends of the prongs are shrunk down over the conduits and are sealed thereto.
