Abstract
A branch-off seal between a heat-recoverable sleeve, such as a tubular or wrap-around sleeve made from cross-linked polymeric material, and two or more substrates such as electrical cables is effected by using one or more clips the outer legs of which are positioned over the outer surface of the sleeve so as to form as appropriate number of conduits and applying heat to cause the sleeve to shrink about the substrates positioned within the conduits. The preferred clips are formed as a trident, the central leg of which extends into the heat-recoverable sleeve and is provided with a layer of a hot-melt adhesive or another sealant so as to enhance the seal formed at the branch-off.
