A sliding block (8) for securely clamping a clamping tool on an underlying surface, in particular a clamping table (7), which exhibits at least one T-slot shaped clearance (18), having a base (14) which may have a rectangular outline and a clamping plate (15) which exhibits a pair of anchorage continuations (16) which project with respect to the base (14) and are in a symmetrical arrangement. A threaded bore (12) is provided which passes through the base (14) and the clamping plate (15) and receives a fastening bolt (9). The clamping plate (15) has a further pair of anchorage continuations (17) and the base (14) and the clamping plate (15) with the two pairs of anchorage continuations are matched to two T-slot-shaped clearances (18, 19) of different geometry. The two pairs of anchorage continuations (16, 17) on the clamping plate (15) are, with respect to the axis (13) of the threaded bore (12), turned through an angle of 90.degree. with respect to one another.
