Fastening element

Abstract

A fastening element ( 1 ) including a rear grip member ( 11 ) for introduction into the longitudinal spaces ( 17 ) of the mounting rail ( 2 ), in the transport position, and for gripping of holding projections ( 6.1, 6.2 ) arranged in the mounting rail ( 2 ), in the securing position, and a stop ( 12 ) for the front external contact of the mounting rail ( 2 ). The stop ( 12 ) is connected to the rear grip member ( 11; 31; 52; 64 ) by a screw ( 13 ). A spacer element ( 14 ) is arranged with two projections ( 15.1, 15.2 ), between the stop ( 12 ) and the rear grip member ( 11 ), for temporary fixing of the rear grip element ( 11 ), in the transport position. The projections ( 15.1, 15.2 ) are mounted spring-biased on the spacer element ( 14 ).
