A fixing device for bone fractures having at least two tensioning elements, at least two fastening elements and at least two sleeve elements. Each of the tensioning elements has a contoured body and has, at ends mutually spaced apart in the longitudinal direction, receivers which enclose sleeve elements and/or fastening elements, so that by linking a plurality of tensioning elements, sleeve elements and/or fastening elements they can be arranged into a chain. Each tensioning element is formed with mirror-symmetry with respect to the longitudinal direction, wherein the receivers extend, starting from an imaginary center line of each tensioning element in longitudinal direction, upwards or downwards to the outer edge of the contoured body of the tensioning element in the height direction and have a toothing system on their contact surface facing the imaginary center line. When connecting individual tensioning elements, these can be aligned with respect to one another in a predetermined angular position by mutual engagement of the toothing system formed on mutually facing contact surfaces of the receivers.
