The fastening of a support rail (1) for a photovoltaic module onto a trapezoidal rib (3) of a trapezoidal sheet (5) comprises a material-efficient retaining element (8). The retaining element (8) has a fastening section (10), which is fastened either on the left or right to a slanted side (15a) of the rib (3). An engaging extension is irremovably arranged on the fastening section (10). In an engaging position, the engaging extension reaches behind a groove (6) in the underside (20) of the support rail (1). In a loose position rotated from the engaging position, the engaging extension can be inserted through the groove opening into the groove (6). The support rail (1) can be held against the upper side (17) of the rib (3) by means of the engaging extension. |
