Abstract

La présente invention permet, lors de l'extraction, à partir d'une extrémité, d'un faisceau de câbles ayant été introduit dans une gaine métallique, et de l'introduction du faisceau de câbles dans un tube ondulé, d'éviter que le faisceau de câbles ne subisse de dommage, ledit dommage résultant d'une mise en contact des câbles électriques du faisceau de câbles avec un bord d'extrémité du tube métallique. L'invention permet également de placer de manière fiable la section d'extrémité du tube ondulé et de la fixer facilement. Une section formant couverture de bord destinée à couvrir le bord d'extrémité de la gaine métallique est prévue dans une position intermédiaire dans le sens axial d'un dispositif de protection; une section sensiblement cylindrique, qui s'étend de la section formant couverture de bord jusqu'à une première extrémité du dispositif de protection dans le sens axial, est utilisée comme section de mise en prise de la gaine métallique, qui doit pénétrer dans une extrémité de la gaine métallique; une section sensiblement cylindrique, qui s'étend de la section formant couverture de bord jusqu'à l'autre extrémité du dispositif de protection dans le sens axial, est utilisée comme section de mise en prise du tube ondulé, qui doit pénétrer dans une extrémité du tube ondulé, et une section ondulée est prévue sur la surface de circonférence externe de la section de mise en prise du tube ondulé de manière à se mettre en prise avec les parties formant sommet ou formant creux prévues sur une section d'extrémité du tube ondulé.
