A pipe socket comprising a sleeve (2), an end portion (8) of a pipe (10) of thermoplastic material, an outer sealing ring (4) and an inner sealing ring (6). The sleeve (2) constitutes the inner surface of the pipe socket, and the end portion (8) of the pipe is molded around the sleeve. The outer sealing ring (4) is positioned between the inner surface of the pipe end portion and the outer surface of the sleeve for sealing the pipe end portion and the sleeve in relation to each other, and the inner sealing ring (6) is adapted to seal the space between the inner surface of the pipe socket and the outer surface of a spigot end of a connecting pipe introduced into the socket. The outer sealing ring (4) and the inner sealing ring (6) are connected with each other. The invention also relates to a method of manufacturing a pipe socket (FIG. 1).
