摘要： The inventive composite gland sealing for the interlocking coupling of a housing end piece (8) comprising an anchoring groove (82), a plastic ring (14) and several locking inserts (20). Each locking insert (20) comprises a radially external head (30) provided with a first front projection (50, 52) applicable against the annular front surface (90) of the anchoring groove (82). The head (30) comprises a second frontal projection (52, 50) radially shifted from the first front projection (50, 52). Said invention is used for cast-iron pipe joint.

摘要： This assembly between a spigot and a socket comprises a sealing gasket provided with a locking insert which comprises a head (30) and a foot. The head (30) comprises a radial projection (40), designed to press against a bottom surface (92) of an anchoring groove (82) belonging to the socket and a first inclined projection (50), designed to press against an inclined surface (91) of the anchoring groove (82). The head (30) also comprises a frontal projection (52) which is offset from the first inclined projection (50) and designed to press against an annular frontal surface (90) of the anchoring groove (82). Application to the connecting of cast iron pipes.
