ABSTRACT:
A fall prevention device for a vertical cable includes a body with a gutter for guiding the cable. The body supports a pin on which is articulated a lever one end of which ends in a cam which can clamp the cable against the bottom of the gutter and the other end of which is fastened to a ring. The cam is spring-loaded against the cable. A knurled wheel cooperating at all times with the cable rotates on a pin above the articulation axis of the lever. The ring has lateral teeth and is mounted to pivot on the lever so that, when the ring is pushed, the teeth can be caused to engage with the knurled wheel.
