ABSTRACT:
A closure for a splice region in cable and method of making it by providing a plastic moulding around the cable jacket. A fluid-tight seal between the moulding and the jacket has inner and outer layers of different materials which eliminate the need to fuse the moulding to the jacket to provide a seal. The inner layer is a compressibly deformable material surrounding and contacting the jacket. The outer layer surrounds the inner layer and is in a circumferentially resiliently stretched condition to compress the deformable material into intimate contact with the jacket and form a first seal region. The deformable layer has an annular portion engaging and fused to the plastic moulding to form a second seal region. The seat is suitable for pressurized and non-pressurized cable.
