The arrangement can be used for clamping a sheet (2) to a base (1). A bolt (6) is guided through bores (4,3) in both parts and from below into a hollow bolt (11) with a threaded inner surface and a transversal bore at the upper end also accommodating a bolt (12) serving as a rotation axle. The lever (13), to be moved around the bolt (12), is provided with a step serving as a stop. A nut (9) with a stepped inner surface and positioned on top of the sheet (2) can be used for adjusting the height of the lever (13) in combination with a washer (10). |
