THE CLAMP FOR AN EXTERNAL FIXATION DEVICE COMPRISES A PARALLELIPIPEDIC BASIC BODY (1) FITTED WITH A FIRST AND CONTINUOUS BOREHOLE (2) RECEIVING A LONGITUDINAL SUPPORT (3) AND A SECOND, CONTINUOUS BOREHOLE (4) RUNNING PERPENDICULARLY TO THE FIRST BOREHOLE (2) AND PARTLY PASSING THROUGH IT. A TENSION BOLT (5) FITTED WITH A HEAD (6) IS INSERTABLE BY ITS FREE END (7) INTO THE SECOND BOREHOLE (4), AND ITS HEAD (6) FORMS A STOP AGAINST THE BASIC BODY (1). AT ITS FREE END (7), THE TENSION BOLT (5) IS FITTED WITH A THREAD (8) TO ENGAGE A NUT (9) FORMING A STOP AGAINST THE BASIC BODY (1). UNDERNEATH ITS HEAD (6), THE TENSION BOLT (5) COMPRISES A TRANSVERSE BOREHOLE (10) RECEIVING A BONE FIXATION DEVICE (11). BY MEANS OF THE NUT (9), THE TRANSVERSE BOREHOLE (10) CAN BE MOVED INTO THE ZONE OF THE SECOND BOREHOLE (4), AND IN THE PROCESS A BONE FIXATION DEVICE (11) INSERTED INTO THE TRANSVERSE BOREHOLE (2) CAN BE MADE TO REST AGAINST THE BASIC BODY (1). THE BASIC BODY (1) FURTHERMORE COMPRISES A THREADED BOREHOLE (12) CROSSING BOTH THE FIRST AND SECOND BORE HOLES (2, 4) AND TERMINATING IN THE SECOND, CONTINUOUS BOREHOLE (4), AND RECEIVING A FIXATION SCREW (13). THE DIAMETER OF THE TENSION BOLT (5) IS LESS THAN THE DIAMETER OF THE SECOND BOREHOLE (4) AND THE TENSION BOLT (5) CAN BE MOVED BY THE FIXATION SCREW (13) INTO THE ZONE OF THE SECOND BOREHOLE (2) TO REST TANGENTIALLY AGAINST THE LONGITUDINAL SUPPORT (3).
