Abstract
To connect two sheaths (1a, 1b), used in prestressing cable technology for concrete supporting structures, there is a coupling element (19) which is fitted with chamfered flanges (6). The sheaths (1a, 1b), which have protrusions (2a, 2b), are each inserted into the coupling element (19) with a tubular element (4) which forms the end of the sheaths (1a, 1b). A sealing ring (7) is inserted between each of the flanges (6) and protrusions (2a) of the sheaths (1a, 1b). The flanges (6) and the protrusions (2a) are held together by sloping surfaces (10a) and (10b) of a groove worked in each socket (8). Each of the sockets (8) consists of two half portions (8a) and (8b), which can be connected together.
