Reinforced sealing ring for reception in a pipe joint between an annular groove-carrying socket end and an insert end. The sealing ring consists of a main body of rubber in which there is embedded an upsplit steel ring. The sealing ring is adapted to be elastically deformable to such a degree that it can be snapped into place in the annular groove of the socket end by a simple mounting operation while it can be prevented from being torn or pressed unintentionally outwards from the annular groove after mounting. In order to achieve this the main body has a largest external diameter of between 1.08D+16 mm and 1.04D+8 mm, while the cross-sectional diameter or thickness of the steel ring is between 0.01D+2 mm and 0.005D+1 mm, where D constitutes the diameter of the pipe. The steel ring is disposed embedded in a central and/or radially outer cross-sectional portion of the main body.
