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.
