Abstract: A sealing device for a sealing space defined by sealing surfaces of two elements (2, 6), preferably pipes or well rings consisting of concrete, comprises a sealing element (28). The sealing element is adapted to seal a section of the sealing space extending transversely of the jointing direction of the two elements and has prior to the jointing of the elements a substantially C-shaped cross section.

Abstract: A pipe joint comprising two sealing surfaces (6, 36) one positioned on each of two end portions (2, 4) of two pipes and a sealing device comprising a sealing ring (18). The sealing surfaces (6, 36) form a cylindrical sealing space in which the sealing ring (18) is compressed. In connection with the sealing ring there is in one of the pipe end portions arranged a circumferential cavity (34) partially receiving the elastic material of the sealing ring (18). The sealing surfaces (6, 36) form sealing space portions having a small and substantially equal space width on either side of the sealing ring (18) in the axial direction of the joint for forming supports for carrying transverse loads on either side of the sealing ring.
