ABSTRACT:
A longitudinally divided cable sleeve which is composed of a shrinkable sleeve member of a shrinkable material having a bead on each edge for engagement with a sealing bar to form a sealing system characterized by each of the beads having a non-shrinkable longitudinally extending strengthening element embedded therein and the sealing bar having a pair of side elements interconnected by a central web, said side elements projecting from the central web to form an undercut groove on each side of said web so that the sealing bar is a cross-sectional configuration of a pair of C-shaped profiles facing in opposite directions and each groove receives one bead of the sleeve member to close said cable sleeve. The sealing bar is preferably made of a material having a good heat conduction property to improve the heating of the inner sealing zones during a shrinking process. If desired, a coating of a fusible adhesive can be applied in the area of the sealing zones to increase the sealing effect.
