ABSTRACT A heat-recoverable article to be positioned around a pipe or cable joint or splice which it is desired to encapsulate or seal provides a means for sealing a splice involving a plurality of cables of the same or varying sizes. The article includes a closure means for holding the article together after it has been positioned around the splice to be sealed. In one embodi- ment, the inner surface of the article contains a heat activated adhesive or sealant to encapsulate the splice and the outer layer of the article is a heat recoverable insulating material. The article may have self-contained heating means comprising a polymeric material having dispersed therein a conductive filler, and exhibiting a positive temperature coefficient of resistance so as to render it self-regulating, the article need only be con- nected to a suitable electric power supply to cause it to recover.
