ABSTRACT OF THE DISCLOSURE A gasket of rubber or a similar material for sealing joints between the sealing surfaces of two members to be joined, for example pipe sections comprising a spigot and a socket part. The gasket is placed in a fixed position on the sealing surface of one of the members, and for assembly of the members the sealing surfaces of both members are displaced substantially parallel to each other fox squeezing the gasket therebetween due to displacement of portions of the gasket relative to other gasket portions. The gasket portions which during the installation of the members are displaced relative to each other define one or more closed very narrow slits extending in the longitudinal direction of the gasket. The width of the slits is so small that the said gasket portions whilst being displaced during the installation are constantly in contact and slide along each other. Further, the slits between the said portions of the gasket are so arranged that the said portions are displaced relative to each other during the installation without being bent, whereas the width of the gasket is reduced. When the said portions are displaced along each other in the opposite direction they become clenched and offer a large resistance to the displacement and produce a large packing pressure.
