A cable splice closure comprises a base (10) having ports (16) for the entry of cables to be spliced, and a tubular cover (30) for sliding axially over a peripheral surface (18) of the base (10), the surface (18) being formed with a groove (20) which tapers towards the end from which the cover (30) is applied and which carries an O-ring seal (24) that is engaged by the cover (30) and which rolls along the tapering surface of the groove (20) as the cover (30) is slid onto the base (10). Thus, as the tubular cover (30) is slid onto the base (10), the O-ring is rolled into a position where it is more firmly gripped between the cover (30) and base (10), to seal more effectively. |
