Device for sealing hollow-cylindrical through-openings for cables, pipes or the like

摘要

In the case of a device for sealing hollow-cylindrical through-openings for cables, pipes or the like, in the form of a double sleeve (11) having a cylindrical outer region and inner region which are integrally connected to one another at one end, at least the inner region (6) which rests on the cable or pipe sheath or on the outer surface of the body passed through it being capable of being shrunk by heat, and the outer region resting on the inner surface of the hollow cylinder being provided with a fusion-adhesive coating, it is intended to create a solution by means of which, in particular, assembly is simplified while at the same time maintaining an optimum sealing effect after the installation, and by means of which cost-effective production is made possible. This is achieved in that the inner surface (12) of the double sleeve (11) facing away from the fusion-adhesive coating (9) is equipped with an expanding element (13) which is subjected to prestressing. <IMAGE>
