Abstract

The plastic pipe (1) has an access branch (3) for unblocking purposes with a plastic closure cap (5) and seal ring (7). The cap is internally provided with an annular chamber (9) to receive the seal ring, which chamber has a narrow portion to retain the ring. The in wall may have a portion which is inclined outwards toward the open chamber end. It may be inclined over its entire height, or have a cylindrical upper portion and an inclined rim portion. The bottom of the chamber may be provided with projections. The ring contained in the chamber may extend to the rim of the inner chamber wall. The width of the open chamber end may be at least equal to the wall thickness (13) of the branch.
