The invention relates to a clamping tool com-prising a clamping jaw ( 5 ), which 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 po-sition. 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 clamping 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 to 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 manner 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 ).
