A heat-recoverable wrap-around device made from heat-shrinkable sheet material is provided with mechanical retaining means which co-operate with opposed edge regions of the sheet material so that after recovery about a substrate such as an electrical cable, the device lies substantially flush with the substrate without protuberances. The mechanical retaining means is preferably a buckle which is shaped to conform with the substrate and in which the sheet material is held by frictional forces. |
