摘要： A plastic pipe part 1 is pushed across a head part 3 of a sealing sleeve 4, being supported by a support 8, thereby providing the plastic pipe part with a widened end 7. Subsequently the widened end is surrounded by an outer mold 11 with three successive widenings 12, 14, 15 and by means of a fluid pressure in the interior of the widened end 7, sealed by the head part 3, the widened end is provided with three socket end widenings 28, 22, 29. After removal of the support 8 the end portion 6 of the socket end is inwardly rebent around the head part 3 thus forming a groove chamber 5 retaining the head part 3 of sealing sleeve 4. Pushing the plastic pipe part across the head part is facilitated by applying a fluid pressure. An apparatus for performing this method comprises an outer mold 5 with three successive mold widenings 12, 14, 15, a first mandrel 20, a second mandrel 21, a third mandrel 30, a fourth mandrel 31, a removable support mandrel 8, a rebending member 26 and a supply conduit 10 for supplying a fluid under pressure in the space between outer mold 11 and the mandrels 30, 20, 21.
