Abstract
Le système selon la présente invention comprend un cordage d'extraction (20) qui comporte une partie agrandie spéciale (21) à une de ses extrémités et que l'on fait passer à travers les alésages traversants centraux (17) des broches d'articulation des charnières des colliers de support de la série, ces broches se présentant sous la forme de deux demi-broches (16, 17) accouplées. Une traction exercée sur le cordage depuis la surface de l'eau permet d'expulser des colliers de support les broches qui s'ouvrent et libèrent ainsi le cordage après avoir libéré les colliers de support.
