The annular seal ring e.g. for large diameter concrete water or sewer pipes has an internal bore (13) with a series of anchorage ribs (14) which fits over the cylindrical end of the male pipe end. The outer part of the seal consists of two mouldings (22,23) with inclined prismatic cross-sections, the outside diameters of which are significantly less than the bore of the female pipe end. A folding groove (27) is provided between the mouldings. The rear face of the seal (19) butts up against a shoulder on the male pipe end. The seal incorporates an inelastic reinforcement hoop (33) under the smaller lip moulding (22).
