Abstract

L'invention concerne un système (20) et un procédé de fixation de câble comprenant un câble (10), une boucle (30, 230) de matériau initialement plus grande qu'un diamètre externe du câble (10), la boucle (30, 230) comprenant des oreilles s'étendant vers l'extérieur (48), les oreilles (48) ayant des extrémités libres distales (50). Une plaque de fixation (60, 260) comprenant une fente à ouverture progressive (62, 262) met en prise les oreilles (48), et rapproche les oreilles (48) lorsque les oreilles (48) sont déplacées longitudinalement dans la fente (62, 262), réduisant ainsi le diamètre de la boucle. Un dispositif de retenue (80, 280) retient la boucle (30, 230) en position autour du câble (10). La plaque de fixation (60, 260) et/ou le dispositif de retenue (80, 280) peuvent être montés sur un équipement de télécommunications (400) pour retenir le ou les câbles.
