ABSTRACT:
A sealing ring for sealing the space between two substantially coaxial sealing surfaces which are axially insertable one in the other to a jointed position, especially for sealing the annular space between socket and spigot end of a pipe joint, comprises a first sealing portion (2) and a second sealing portion (4). The sealing portions are adapted at the axial insertion movement substantially stationary to engage one surface each of said sealing surfaces and to slide against each other. The first and the second sealing portion are by means of a releasable and/or substantially expensible connector portion (6) connected with each other at least at the front side of the sealing ring in respect of the direction of insertion movement of the second sealing surface during the jointing of the sealing surfaces.
