Un outil de câblage (10) de la présente invention se présente sous la forme d'une plaque nervurée et est doté d'une section (1) d'embase et d'une section (2) de couvercle, entre lesquelles sont insérés des câbles (9). La section (1) d'embase comporte une section (11) de câblage qui fait face à l'espace de câblage, une première section étagée (12) qui se situe le long du bord extérieur de la section (11) de câblage, une première section (13) de cadre qui forme le bord extérieur de la section (1) d'embase et une section (14) de fixation de câbles qui fixe les câbles (9) à la première section (13) de cadre. La section (2) de couvercle comporte une section (21) de paroi en vis-à-vis qui fait face à la section (11) de câblage, une deuxième section étagée (22) qui se situe du côté opposé à la section (1) d'embase le long du bord extérieur de la section (21) de paroi en vis-à-vis, et une deuxième section (23) de cadre qui forme la partie de bord extérieur de la section (2) de couvercle. La section (1) d'embase et la section (2) de couvercle sont obtenues en moulant sous vide un élément en résine de forme aplatie.
