The invention relates to a fastening device (1) for fastening at least one mounting element to a threaded bolt (6), comprising a nut (2) having a threaded bore (7) and a clamping element (3) that interacts with the nut (2) and has an opening (8), wherein the nut (2) has a conical supporting region (9) on the outside thereof, by means of which, in the mounted state, the nut engages at least partly in the opening (8) of the clamping element (3) and there rests on a complimentary inner cone (10) which the clamping element (3) has, and wherein the nut (2) has at least one slot (12) which interrupts the nut wall over a sub region of the axial extent of the latter, wherein the at least one slot (12) opens at the axial end of the nut (2) which is located closer to the larger diameter than to the smaller diameter of the conical supporting region (9) and which is designated as the top end, wherein the at least one slot (12), starting from there, extends over a length which is between 20% and 95% of the entire axial length of the nut (2), and wherein a sub region of the clamping element (3) has an external thread (26), by means of which the clamping element can be screwed into a mounting element. |
