A blocking unit is provided, which is attached to the safety runner and is passivated during normal climbing and activated during fall. The blocking unit has a two-arm ratchet lever (10) that is pivoted on a runner-side rotary axis (9) with an inner arm (13) and an outer arm (14). The inner arm and the outer arm of the ratchet lever are counter-rotating.
