A plastic sleeve (2) for plastic pipes (1, 3) or fittings, in particular for high-pressure water pipes, has at least one ring-shaped groove (6) for receiving a sealing ring (8) that presses a pipe end (3) inserted into the plastic sleeve (2). A clip (9) that surrounds the outside of the sleeve (2) at least in the area of the ring-shaped groove (6) is provided to maintain the sealing ring (8) under a constant radial prestress by pressing together the sleeve (2). |
