Abrégé

The invention relates to a slider for a climbing protection system as fall protection for persons on ladders having a C-profiled guide rail. The slider comprises a slider body (14), a detent pawl (11), and a first and second roller pair (15, 21) for guiding the slider (10) in the guide rail. The first roller pair (15) can be twisted relative to the slider body (14). In order to be able to attach the slider in any position to the guide rail and to ease operating both by left-handed and right- handed persons, the second roller pair (21) is mounted on a slider carriage (30) connected to the slider body (14) tiltably about a tilt axis running parallel to the rotation axis of the second roller pair (21), and/or in that the rollers (21A) of the second roller pair (21) are arranged on a shaft (27) mounted floatingly on the slider (10).
