In the present invention, there is disclosed an assembly element comprised of a body (1) with an offset (2), wherein the body (1) is provided with at least one side groove (3) for making an elastic periphery (4) of the body (1). In said offset (2), there is performed at least one opening (5) with a conical run-out reaching in the axis of the side groove (3). This opening (5) is intended for an expansion element (6) and can be provided with thread. In said offset (2), there is further performed at least one assembly aperture (7) for fastening another structural part. The elastic peripheries (4) are preferably roughened on their outer circumference or provided with grooves, optionally a hard surface coating to increase strength of a shape joint. |
