In the covering sections spaced apart clamps are arranged. Theses clamps comprise a C-shaped clamp component with C-stem (7) and two C-arms, a pressure piece in the form of a two-armed lever and a clamp screw, which acts upon the pressure piece related to the C-stem, which is linked to the flanges (4) located one in the other. The pressure piece is formed as a bent lever (9), which is angled to the flanges in the area before the C-stem. The bent lever, the C-stem and the bent lever forced guide device (12) are so matched, that by increasing the clamping force, the bent lever is activated. |
