Abstract

The invention relates to a device for works in for instance pipelines, which device (1) is intended to be introduced into a pipe (100) to a desired position and after that by means of a pressure medium be temporarily activated to a fixed engagement with the inner surface of a surrounding pipe. The device (1) comprises at least one ring (15) of swelling body, which is brought to expand diametrically when influenced by the pressure medium. Radially outside the ring (15) of swelling body there is arranged a gripping ring (17), which is moved radially outwards to a pressing contact against the inner surface of the pipe (100) when the ring of swelling body is influenced by the pressure medium. The device (1) according to the invention is provided with docking devices (32, 33) in order to make docking to different fittings possible and is in the first place intended to be used for relining works in pipelines.
