ABSTRACT:
A sealing ring for sealing a space between the outer surface of a spigot end and the inner surface of a socket end in a pipe joint comprises an annular sealing element consisting of elastomeric material and a substantially annular locking element consisting of a rigid or semi-rigid material. The locking element is divided at at least one point of its periphery and constitute at this point two spaced portions. Between these portions there is positioned a connecting element consisting of a material which is substantially more elastic than the material of the locking element.
