Abstract
The device for allowing a person to safely step off from and onto a climbing track on a roof edge, a roof slope, a shaft opening or similar, includes a guide rail (10) for guiding a catching device to which a person using the climbing path can be secured, and an extension piece (24) of the guide rail (10). The extension piece (24) of the guide rail (10) can be moved between a first and a second position, the extension piece (24) being so arranged in the first position that it does not project above the guide rail (10), and being aligned in longitudinal direction with the guide rail in the second position. The extension piece (24) can be guided displaceable along the guide rail (10) and at a distance from the latter and can be swivelled by 180.degree. in the final position, which corresponds to the second position, so that it is in alignment with the extension (10).
