A system is provided for the rapid change, among others, of clamping jaws on a machine-tool which comprises self-blocking means for locking a jaw for clamping a workpiece from the inside or a jaw for clamping a workpiece from the outside. The jaw-holder is provided with at least two bearing portions for said jaws, the bearing faces being slanted through an angle .alpha. and .gamma. respectively. These faces cooperate in the blocked position with corresponding bearing faces of the jaws. One of the ends of an assembly has a face slanted through an angle .beta. whereas another face is slanted through an angle .delta.. These faces cooperate in the blocked position with a corresponding bearing face respectively of one of the jaws.
