Electrically heat-recoverable sleeve

摘要

A branch-off between telecommunications cables (5) may be sealed by means of an electrically heat-recoverable sleeve (1) and a branch-off clip (2) which holds together circumferentially spaced portions of the sleeve (1) between the branching cables (5). The clip (2) has an inner leg of heat-activatable sealing material which in use is positioned in the sleeve (1) between the cables (5). The sealing material is activated by the heat generated in the sleeve (1) during recovery.
