Abstract

L'invention concerne un arrangement (1) pour connecter un premier élément de ligne (2) à un deuxième élément de ligne (3) qui peuvent être connectés l'un à l'autre de manière amovible. Un élément de connexion en forme de manchon (5) est formé sur le deuxième élément de ligne (3). Lors de la connexion du premier élément de ligne (2) au deuxième élément de ligne, le premier élément de ligne (2) vient en prise dans l'élément de connexion en forme de manchon (5). Une pince (4) servant à la fixation axiale amovible du premier élément de ligne (2) se trouve sur l'élément de connexion en forme de manchon (5). La pince (4) repose contre une butée (7) formée sur le pourtour du premier élément de ligne (2), ce qui empêche une extraction du premier élément de ligne (2) hors de l'élément de connexion en forme de manchon (5) dans une direction axiale (A).
