This pipe anchor is used in the underground extraction of mineral resources, in underground mining and tunnel construction works. It makes it possible to assembly elements whose length exceeds that of the underground work, without assembly efforts and special equipment. The pipe anchor consists of a body (1) with an inner hollow and a plate (5) in its back end. The body (1) is formed out of two freely detachable parts (2) with profiling ends (3) incorporated in a bushing (6) and ending with an anchor head (4) in contact with the plate (5). The inner hollow of the body (1) is filled with an expanding substance (13), for example polymer based.
