The inventive device is used for treating bone fractures and/or for fixing surgical implants, surgical threads or tissues in or on the bone and essentially comprises a closing element (1) and a rivet (2). Coaxially to a central axis (6), the rivet has a rivet shaft (3), a rear end (18) which intersects said central axis (6), a front shaft end (7) which is axially opposed to said rear end (18) and a through opening (5) which penetrates the rivet (2) coaxially, so that the shaft (10) of the closing element (1) is coaxially displaceable in the through opening (5) and the head (11) can be axially brought to rest on the front shaft end (7). The rivet shaft (3) also comprises at least two grooves (9) on the outside, these grooves extending from the front shaft (7) in the direction of the rear end (18), parallel to the central axis (6).
