Abstract

In forming a sealed enclosure around a cable branch-off, a generally U-shaped clip is applied to an end of a heat-shrinkable sleeve positioned around the branch-off, and heat is applied to shrink the sleeve. The clip is formed of an electrically insulating material resistant to the high temperatures of a torch used to apply heat to shrink the sleeve, e.g. a thermally resistant aromatic polymer.
