DEVICE FOR COUPLING TWO TUBULAR ELEMENTS

摘要

The invention relates to a device for coupling two tubular elements (1, 4) of an anchor rod, wherein a first element (1) is provided at one end (2) with an external thread (3) which may be screwed into a complementary inner thread (6) of a collar end (5) of a second element (4) for connecting thereto extending over the end (2) of the first element (1). The collar end (5) of the second element (4) is provided with at least one profiling (9) on the front face (8) thereof facing the first element (1) which may be brought into engagement with at last one profiling (17) on the outer periphery of the end (2) of the first element (1), the cooperating profiles (9, 17) providing a rotational lock of the ends (2, 5) of the tow elements (4) to be screwed together in the tightening direction at least in the essentially completely screwed-in state and thus provide in a simple and reliable manner a rotational lock between two elements (1, 4) for coupling or screwing together.
