The fastening device (5) for the releasable fastening of a strut (3a-3d) to a column (1) comprises a retainer ring (7), attachable to the column (1), and a connecting element (9a-9d) for connecting the strut (3a-3d) to the retainer ring (7). The connecting element (9a-9d) has at one of its ends diametrically opposed jaws (33a, 33b) which extend around the lateral surfaces (16a) of the retainer ring (7) whereby the strut (3a-3d) is fastened to the column (1) safe from twisting even with respect to large torques and bending moments. The exact horizontal position of the strut or struts (3a-3d) can be adjusted by rotating the retainer ring (7). |
