The invention relates to a clamping tool comprising a clamping jaw (5), whic h is releasably fixed on a rail, preferably at the end (2) thereof, and which comprises a pin (4) that passes through an opening of the rail. The clamping jaw is releasably fixed on the rail, whereby, after pulling the pin (4) out of the opening, the clamping jaw can be fixed at an opening (3) located at another position of the rail, preferably at its other end by reinserting the pin into an opening (3) located at that position. A second clamping jaw (7) is displaceably arranged on said rail (1). A tightening element (8) is used to bring the second clamping jaw, according to the location of the first clampi ng jaw (5) on the rail (1), into a clamping position in the direction of the latter or in a direction away from the latter. The aim of the invention is t o achieve a simplified changing from one fixing position to another fixing position on the rail. To this end, the pin (4) is assigned in a captive mann er to the first clamping jaw (5) and is held i the engaged position inside the opening by the force exerted by a spring (9) that is tensioned when the bolt is pulled out of the opening (3).
