Patent attributes
A fastening system (1) comprises a rear grip part (5) for introduction into a mounting opening (4) of an elongated mounting rail (2) in a first position and for gripping behind the mounting projections (6.1, 6.2) in a second position and a stop (3) for frontal external loading of the mounting rail (2). The stop (3) is connected to the rear grip part (5) by means of a threaded bolt (9). In addition, on the fastening system (1) a system is provided for providing a relative rotary movement between the stop (3) and the rear grip part (5) about the axis of the bolt (9). The system is configured as a transmission system for transforming a translatory movement of the bolt (9) relative to the stop (3) into a rotary movement of the rear grip part (5) relative to the stop (3).
