Abstract: The present invention concerns a sleeve (1) for cable entries, pipe penetrations etc. The sleeve (1) has a central part (3) with a through central opening and one flange (2) at one end of the central part (3). The flange (2) is directed radially away from the central part (3). A compressible part (4) is arranged the flange (2) and a compression means (5), here in the form of a ring. The ring is arranged slidable on the outside of the central part (3). By means of screws (6) the compression means (5) may be forced towards the flange (2) of the central part (3), compressing the compressible part (4). By means of the compression of the compressible part (4) the sleeve (1) is fixed to a plate (7) or the like.
