A sealing ring (14) is adapted to seal an annular gap (15) between a socket end (11) and a spigot end (12), the socket end having a circumferential groove (13) for receiving the sealing ring. Due to manufacturing tolerances, the radius of the groove (13) is between a minimum value R'min and a maximum value R'max, and the radial gap width of gap (15) is between a minimum value Tmin and a maximum value Tmax. The sealing ring (14) comprises a sealing element (16) and a holding element (17) which is connected thereto and which is more rigid than the sealing element (16) but is so elastically deformable as to allow insertion of the sealing ring (14) into the groove (13). The sealing element (16) comprises a first sealing part for sealing against the socket end (11) and a second sealing part (19) for sealing against the spigot end (12). The first sealing part has a neck portion (18a), which supports a radially outer head portion (18b), whose outer radius is slightly greater than R'max, the first sealing part (18) being, at the level of the neck portion (18a), bendable in the axial direction (P) along which the spigot end (12) is to be inserted into the socket end (11). The cross-section of the annular holding element (17) has a radial extent which is greater than 2xTmax.
