Abstract
An energy absorbing device for a safety device with a rope, comprises a metal body equipped with a first orifice of ellipsoidal shape allowing two strands of rope to cross without clearance, and a second reverse V-shaped orifice of decreasing cross-section in the direction of the first orifice. The second orifice has a portion of reduced width of a smaller dimension than the diameter of the rope, and two convergent edges for centering the rope when the turn is tightened during sliding. The lanyard may be used for rock-climbing, or for working at heights.
