ABSTRACT:
A pipe coupling for interconnecting pipes experiencing length changes, comprising a sealing gasket enclosed within a housing and having a substantially C-shaped cross-sectional configuration and open towards the inside. The end faces of end sections of the sealing gasket which merge at the web of the sealing gasket are each clamped, by means of a compression spring arranged within the sealing gasket, against a related substantially ring-shaped support disk which, in turn, is axially movable in conjunction with the one or other pipe with which such corresponding support disk is operatively associated.
