Heat shrink sleeving sealing for cables - utilises shaped interlocking forms in longitudinal edges of sleeving

The heat shrink sleeve is for cables or tubes and is wrapped around at the ends which are fixed together by C-shaped forms in the sleeve which interlock. An inner support overcomes difficulties of assembly of earlier methods and provides good retention of the longitudinal edges. A heat shrink sleeve (1a) has C-shaped swellings (4a, 5a) towards the exterior and close to both the longitudinal edges (2a, 3a). The thickness of material is constant including the area of the swellings. A reinforcing strip (7a) is inserted into the smaller swelling. This contains a wire (7c) which allows the material to give good resistance to compression. The smaller swelling is inserted into the larger when the sleeving is wrapped around the sleeved object. An inner section (7b) of the reinforcing strip is surrounded in glue (17) to provide sealing when heat is applied. The combined swellings are compressed by a C-shaped rail (6a).
