<p>There is disclosed an arrangement for forming a joint between electrical cables, each of which comprises electrical wires enclosed by a cable jacket. The arrangement comprises a connector for forming electrical connections between wires of the cables, a fusible block formed from a thermoplastic polymer, which is capable of being positioned about the connector to enclose the connector and the connected wires and a heat-shrinkable sleeve which can be positioned around the fusible block and proximate ends of the cables and recovered thereon, the sleeve having a recovery temperature of at least 10.degree.C above the melting point of the thermoplastic polymer. A method of forming the joint comprises the steps of forming an electrical connection between wires of the cables, positioning the fusible block about the connected wires to enclose the connected wires and the proximate ends of the cable jackets, and positioning the heat-shrinkable sleeve around the fusible block and the proximate ends of the cables, heating the sleeve and fusible block to cause the sleeve to recover about the fusible block and to cause the fusible block to melt, and then allowing the sleeve and fusible block to cool.</p> |
