ABSTRACT:
Method and arrangement for providing an end connection for pipes made from a rigid, but deformable material. An end connection includes a pipe casing (1) that protrudes into a pipe end (15). The pipe casing has an outer mantle surface extending symmetrically around a longitudinal axis (9), to yield a surface (2) of substantially circular cross section having a diameter allowing the pipe end to be applied over the pipe casing. The mantle surface has two recessed parts (3, 4) running peripherally therearound to receive embossed parts (24, 25) of the pipe end (15) for rotational movement between the pipe end and the pipe casing (1). A sealing member (13), between the recessed parts (3, 4), seals a portion of the space between the outer mantle surface and the pipe end.
