Abstract: This fixing clamp for straightening the bodywork of accident-damaged automobiles, and in particular the sheet metal seats for MacPherson suspension heads, is characterized by a pin provided with threaded axial end bores for receiving eyebolts, and with an intermediate step on which there rests a flange for supporting the sheet metal which is to be repositioned and/or straightened and which comprises a hole through which the pin shank is passed, a further drilled flange then being mounted on the pin, and being clamped against the sheet metal to be straightened by the pressure exerted by a sleeve which carries a positionable transverse fixing clip and is tightened by a nut screwed onto the pin.
