    Abstract: A rope safety device (10,10-1) installed as a sub-roof element on a roof (T), a covering or a similar structure, comprising: a fixing and damping plate (11), perforated, fixed to the roof structure (T): and a rope (12) associated with the fixing and damping plate, wherein the rope (12) has an attachment portion (12a), in the form of an eyelet (12′), via which an operator can attach to the rope (12), so as to operate in a safe condition on the roof on which the device is installed: wherein the plate (11) has a configuration with one or more holes (13, 13b) used to insert the rope (12) and wherein the rope (12) is configured and set with respect to the plate, in whose holes (13b) is inserted, in such a way that the rope (12), when it is subject by the operator, attached to the same rope, to a given traction force (FT), slides (f) along a certain stroke (D) in the holes (13b) of the fixing and damping plate (11) before being retained by the latter. in a further embodiment (10-2), suitable for application in combination with a rope safety line (LS) or life line system, the safety device to the rope (10) can comprise, as an alternative to the plate perforated, a calibrated damp (16), associated with the rope (12) and defining an eyelet (12e) for coupling the device (10, 10-2) to the rope (F) the safety-line, in which the terminal (16) the cable (12) flows (f′) in a controlled way when it is subject, on the part of an operator attached to the same rope (12), to a traction force (FT). Advantageously the device rope safety slide (10, 10-1, 10, 10-2) of the invention, installed on a roof (T) or similar structure, is adapted to dampen and absorb effectively the impact and the stress suffered by an operator, when, being attached to the rope (12) of the device (10) to operate in conditions of safety on the roof (T), accidentally puts into traction and pulls the cable (12) The invention also concerns an innovative guardrail (20) having a metal structure (21) substantially identical to that of a conventional guard rail, and a rope device (22) which is associated with a containment rail (21b) of the metal structure (21) of the guard rail (20) and whose rope (12) is subject to a controlled sliding or slipping when a vehicle skids and hits the guard rail (20), so as to efficaciously absorb and dissipate the impact energy caused by such a collision.
