Device for preventing a fall on a vertical cable, with a channel for guiding the cable, two flanges supporting an axle on which a lever is pivotally mounted, one extremity of the lever including an opening for fixing a link and at the other extremity, a cam which co-operates with the cable in the event that the user falls to block the device along the cable. The flanges are connected via a hinge so that the flanges can be pivoted with respect to each other and moved apart from each other for positioning the device on the cable and closed together whereby the cable is inserted in the channel, and a safety structure is provided to oppose opening of the flanges when the lever does not occupy an angular rest position in which the cam is spaced from the cable. |
