ABSTRACT:
To seal a cable junction, an insert is placed between two branch cables of the junction, which is then enclosed by a heat shrinkable envelope. The insert has at least one insert part having a block of heat fusible material attached by one or more flanges of heat conductive material to the branch cables. The block lies between the branch cables at least partially inside the envelope. Then, when the envelope is heated to cause it to shrink, the block fuses, thus forming a seal. For most sizes of branch cables, two insert parts may be used, but three or more may be used for large branch cables. The flange preferably has a tongue extending into the block to assist heat conduction.
