Wall entrance sealing tube e.g. for cables or conduits

摘要

The sealing tube accommodates service connections (cables, conduits etc.) and is provided with a flange at one end fitted with a cover with openings for the service connections. Each flange (1,3) has a tubular section (2,4) and between the sections there is a connecting sleeve (5,15). The sleeve has two sections (5.1,5.2) one of which overlaps one section of the pipe section and the other is inserted in the other pipe section (nested sections). The facing surfaces of at least two nesting surfaces can have threads which mate and means can be provided for preventing unintentional separation of the individual sections.
