ABSTRACT:
A sealing device on a pipe includes an elastic sealing ring of generally U-shaped cross-section, which is clamped on the pipe by a clamping strap. The U-flanges of the sealing ring are so loaded by the pressure exerted by the clamping strap on the U-web of the sealing ring as to occupy a substantially radial position.
