The insert (4) of the holding device possesses fins (4b) that are arranged according to the shape of a hole so that, after being introduced into the hole, they are form-fitting, and make the hooks (4c) engage at the edge of the hole. The locking piece (3), which fits non-positively to the inside of the fins (4b), fixes the fins (4b) in position. The locking piece (3) in turn is prevented from slipping out unintentionally by the fixing piece (1). Depending on the embodiment, a pretensioning wheel (5) can increase the hold and allow adjustment to different wall thicknesses (7), and a guide sleeve (2) can enable intruments (6) to be guided precisely. |
