The present invention relates to a device for fixation of bone fragments at bone fractures. The device comprises at least two fixation means (1), a securing plate (17), and a securing means for the respective fixation means with a view to achieving a stable rigid connection between fixation means (1) and the securing plate (17) and configuring the device in such a way that the fixation means are not allowed to change their angular position relative to the securing plate and relative to one another, each fixation means (1) has a first fixing portion (9) for fixing the fixation means in an inner bone fragment (3), a second fixing portion for locking the fixation means, which involves using the securing means, to the securing plate (17) which is disposed on the outside of an outer bone fragment (2) and allows movement of the outer bone fragment relative to it, so that the fixation means are prevented from changing their angular position relative to the securing plate and relative to one another, and a middle portion (32) which is situated between the fixing portions and runs through the outer bone fragment, along which middle portion the outer bone fragment can slide inwards towards the inner bone fragment in which the fixation means is fixed.
