Abstract: The invention relates to an adjustable securing means, preferably of metal, for joining two components (1,2) together. It comprises a holding element (3) which can be incorporated into an adapted hole in the component (1) at the side of the component (1) facing the component (2). The holding element (3) is provided with an internal thread and comprises a collar (8). The securing means further comprises a force-transmitting element (7) which is provided at least partially with an external thread and is screwable into the holding element (3) and has a through hole (8) with a stop (a) or the like at one end, the hole (8) being otherwise completely or partially formed with polygonal cross-section. The holding element (3) consists of a relatively narrow sleeve-like ring (6). The internally threaded holding element (3) comprises a lip projecting radially from its peripheral face and axially spaced from the collar and a lug (16) which lies in the plane of the collar (8) opposite the lip (12 ) and has a hole (18).
