FIELD: construction.SUBSTANCE: in the application a device is described for fastening on a bearing element (11), comprising a plastic nut (10), having a body (14), inserted by axial displacement into an extended hole (12) of a bearing element (11). The cross section of the body (14) matches in shape the extended hole (12) and is stretched in the first main direction (Z1), which makes it possible to insert the nut (10) into the hole (12) and stop it in it by means of rotation at a support head (15). Rotation of the nut (10) is limited at least with one support surface. The shape of the support head (15) is identical to the shape of the extended hole (12), and the cross section of the support head is extended in the second main direction (Z2), stretching with angular shift (a) relative to the first main direction (Z1), making from 5° to 25°.EFFECT: support surface is made to limit rotation of a nut relative to an extended hole with an angle practically equal to the specified angular shift, so that during stopping of the nut the head closes the entire extended hole.9 cl, 4 dwg |
