<p>Fixing of an optional element (6) of a plate-like form to the element of a C-section (1) is achieved by means of intermediate elements such as a specially shaped nut (2) which can be inserted on any location into the C-section (1), and a screw (4) with a washer (3). The element (6) which is to be fixed on the C-section (1) is put under the screw (4) and the washer (3). When screwing the screw (4) into the nut (2), the element (6) is pressed against the C-section (1) over the washer (3), and the nut (2) bulge (7) assures an enough strong grip of the nut (2) to the interior edge of the C-section (1) which guarantees a strong and safe connection of the element (6) to the C-section.</p> |
