A safety device that is suitable for being coupled with one or more ropes (70) comprises a supporting structure (2) defining a gap (3) suitable for housing part of said one or more ropes (70) and suitable for coupling with a snap-hook (60), first deflecting means (10) shaped for imposing on one or more ropes (70) a first curve (C1), second deflecting means (13) shaped for imposing on one or more ropes (70) a second curve (C2), third deflecting means (50) shaped for imposing on one or more ropes (70) a third curve (C3) and suitable for cooperating with said snap-hook (60) to lock said one or more ropes (70) in a locking zone (B), and fourth deflecting means (65) fixed to said supporting structure (2) in a stationary position that is distinct from said locking zone (B) and shaped for imposing on one or more ropes (70) a fourth curve (C4) that is variable to control the braking effect of said device (1) on said one or more ropes (70). |
