A pipe connection in which pipe ends are provided with lips or flarings within the area of the joint edges and which includes a clamping ring having a U-shaped profile at the inner surface which is adapted to be tightened radially inwardly; the inner end faces of the clamping ring and/or the end faces of the lips or flarings are inclined toward the pipe axis so that the joining edges are urged toward one another in the tightened condition of the clamping ring; at least the radially outermost ring-shaped part of the clamping ring is provided with at least one plastically deformable, lug-shaped ear which is adapted to be tightened by contraction thereof and thereby establishes a permanent connection which can be reopened only by destruction of the clamping ring.
