Abstract

L'invention concerne un système d'entrée multiple (1) pour introduire au moins une ligne dans une paroi, comprenant une plaque de base (2) et une plaque de serrage (3) pouvant être reliée fonctionnellement à la plaque de base (2). La plaque de base (2) comprend plusieurs premières ouvertures (5) dans la direction axiale, lesdites ouvertures étant coaxiales à plusieurs deuxièmes ouvertures (6) disposées dans la plaque de serrage (3). Un élément de passage (4) est disposé au moins par endroits à l'intérieur des ouvertures de la pluralité de deuxièmes ouvertures. La plaque de base (2) comprend également une collerette périphérique (8) qui fait saillie d'un côté (10) de la plaque de base (2) autour de la pluralité de premières ouvertures (5), ladite collerette présentant une surface d'extrémité distale (9) sur laquelle l'élément de passage respectif s'appuie dans la direction axiale. La collerette (8) est au moins partiellement immergée dans la deuxième ouverture (6) qui est coaxiale à la première ouverture (5) respective lorsque le système d'entrée multiple (1) est à l'état de tension.
