<p>The device i.e. shock absorbing cord (101) or dynamic belay rope, has a status indicator that includes a lengthened relative sliding segment (111) extending mainly longitudinally relative to the cord so as to provider a set of opposite ends offset from one another along the cord. One of the ends is partially decoupled under tension of the cord by sliding of the end relative to the cord when an elongation of the cord is beyond a predetermined threshold.</p> |
