Abstract

A device for positioning a holder for an aiming sleeve for implanted bone nail fasteners with respect to a Roentgen ray source includes a support (25) for supporting the holder (7). A base plate (12) and a pivotable bracket plate (3) receives the support means and is mountable on the housing of the Roentgen ray source for spacedly positioning the holder from the source. The support is formed as a fork-like element (26, 28, 29) retained in sleeves (38, 39) on the bracket plate by means of locking cams (8).
