Abstract

A movable ring, disposed between an elastic conical ring and a fastening cover, has a conical surface which cooperates with that of the elastic ring. An elastic packing is disposed between the movable ring and the pipe end face. A space between the cover and the movable ring is divided into two by a further elastic packing to form two chambers. - One chamber is connected with an external supply of water and the other chamber is connected with the internal pressure of the pipe under test. Corresponding radial cut-outs are made in the cover and in the clamp and are displaced from each other by a fixed angular spacing, to facilitate connection and disconnection of these two parts.
