<p>The device includes a magnet mechanism (10) that generates a magnetic force and is indirectly connected to a magnetizable formwork base (2) through a magnetizable supporting mechanism (20). The device is movable between a first position in which the supporting mechanism transmits the magnetic force to the formwork base to fasten the device to the formwork base, and a second position that interrupts transmission of the magnetic force such that the device may be taken off or adjusted.</p> |
