An arrangement for the watertight insertion of pipes (11) through rooms and house walls of concrete or similar material. The arrangement involves an insertion pipe (14) for insertion into rooms and house walls, which is externally profiled and where at least one end is equipped with an external ring groove (17) in the form of an attached finishing collar (18) made of rubber or the like. This finishing collar has a projecting axial connector piece (20) upon which a surrounding tightening device (23) is placed for the turning of the connector around the pipe in tightening contact with its exterior. An oil nipple (24) can be used on the finishing collar for the application of grease between the connector and the pipe.<IMAGE> |
