The rope is held by grub-screws into some stubs that sit on either end of the passerelle and at the ends of the poles the raise the rope when the passerelle is extended. Part of the rope has elastic shock-cord inside. If that is worn out I think you can only order a new one as the end-pieces on the rope are non-removable. There is a Opacmare dealer in the US if I remember correctly.
