An instrument set for fixing a cord-like implant in a bone comprises a retaining element which can be inserted into the bone. The retaining element comprises a recess for receiving a transverse pin and is also used to fix the implant. In addition, the retaining element comprises a guide for receiving the implant, the guide being configured in such a way that the implant can be guided in a loop formation around the transverse pin distally from the retaining element.
