摘要

The device has a section (5) with a front flange (8) comprising an opening (9) for receiving a back plate (3) in a junction plane between a suction cup (2) and the back plate. The section has two intermediate gripping flanges (10) inside the section in a plane parallel to the junction plane. A mandrel clamp (15) retightens on two opposite sides of the gripping flanges under the pulse of a clamping bolt (16) crossing the back plate.
