A fall-arresting device includes a body which has a runner, two pivoting cams, and a system for actuating at least one of these cams in the event of the user or of a load falling. The body has an elongate opening intended to accommodate the member allowing the user to be harnessed to the device, particularly a shackle, and the two cams are placed some distance apart. The system for actuating the cams includes at least one finger secured to a cam, each finger lying in the path followed by the shackle in said the opening if the user or the load falls. |
