Abstract (en)
[origin: EP0904869A1] The tool has a seal unit (7) with a support ring (12) a sealing element (13), and a stop body (11) fastened to it with a sealing head stop face (4) on a hollow profile (3). The support ring slides on a carrier part (5), which has an actuator (37). The stop body engages on the profile due to an axial movement of the carrier part relative to the support ring, actuator and support ring charges the sealing element to expand it.
