Abstract

The coupling has the pipe end to be connected fixed on a support casing. A phase locates against a matching phase in an aperture of a nipple end. The casing also supports a clamp ring which is split axially. - The ring with the phases locates partly against the support casing and partly against the nut. The clamp ring has an extension which projects out of the nut aperture in the form of a collar, the axial gap of which is obliterated when the nut is tightened.(1)
