<p>The present invention relates to improvements for anti-fall devices that can be directly anchored to metallic covering coat and that in case of fall provide for spreading stresses on the covering coat preventing its damage at the anchoring point; particularly, the improvements relate to the anchoring plate of the device to the cover, and the vertical elements (9,14) supporting the anchoring cable which in case of fall can flatten and bring themselves in the same direction of the fall. This is achieved by enabling a rotation of the elements (9,14) transmitting the stress from the safety line to the metallic covering, both about a vertical and a horizontal axis img id="iaf01" file="imgaf001.tif" wi="168" he="122" img-content="drawing" img-format="tif"/></p> |
