Fixing device for fastening solar panels to a C-shaped mounting rail

摘要

The device has a rear-gripping part (21) with two side pieces (22, 24), where one piece has a width that is larger than the width of an assembly opening. The width of the other piece corresponds to the largest width of the opening. Projections (27) are provided at the width of the latter piece and project from a free end area of the piece (24), where the distance from one projection to the other projection is larger than the width of the opening. A connecting section (16) of a holding-down unit (12) is arranged in a specified angle to the longitudinal axis (34) of the device.
