ABSTRACT:
A centering and clamping device for clamping a support (4) to a base (1) has contact surfaces (29 and 8) which come into contact with each other and have installed therein device parts (5 and 2), with passive (6) and active (3) coupling elements. The device parts have centering elements (31 and 33) which work in conjunction, one of which (31) is designed to yield elastically in the direction of clamping. The active coupling element (3) contained in the base part (2) of the device can be moved between its retracted position within the contact surface (8) of the base (1) and an operating position where it projects above this contact surface. The elastic centering element (31) is a circular collar having a base area, reduced in cross-section, and an S-shape (36) by narrow radial circular grooves (34, 35).
