摘要

Device for coupling two workpiece parts (10, 12) comprises a fixing pin (14) arranged on the first workpiece part and having a cylindrical casing surface and a radially protruding annular planar surface (22) delimiting the fixing pin on its root, a sleeve (16) arranged on the second workpiece part and having a cylindrical inner surface delimiting an annular front surface (24) and a clamping mechanism (20) for drawing the fixing pin into the sleeve and pressing the planar surface against the front surface. An elastically deformable centering ring (29) having an outer conical shape is arranged in the root region of the fixing pin. Preferred Features: The centering ring is placed on the fixing pin. A recess (36) for receiving the centering ring surrounds the fixing pin.
