Abstract

L'invention concerne un dispositif de connexion de purge améliorant l'efficacité des opérations de connexion de tuyau de purge. Cet objet est atteint en améliorant l'efficacité des opérations de connexion du tuyau de purge à une pièce tubulaire de connexion permettant de purger l'eau à partir d'un égouttoir, empêchant toute fuite d'eau après la connexion, et faisant en sorte que le tuyau de purge ne se déloge pas facilement pendant la connexion. Des parties saillantes (21 à 24) sont formées à la surface périphérique externe d'un manchon cylindrique (20) fixé sans serrage dans la pièce de connexion cylindrique (10) du tuyau de purge (4). Lorsque le tuyau de purge (4) subit une traction avec la pièce tubulaire de connexion (3) avec ajustement serré dans le manchon (20), la surface saillante (15) du tuyau de purge (4) au niveau de l'extrémité avant de la pièce de connexion (10) est au contact de la surface d'extrémité avant de la partie saillante (21) du manchon (20). La surface périphérique interne de la pièce de connexion (10) et la surface périphérique externe de la partie saillante (21) reçoivent une pression superficielle, et la surface saillante (15) au niveau de l'extrémité avant de la pièce de connexion (10) est en contact étroit avec la surface d'extrémité avant du manchon (20) sur le côté partie saillante (21). Ainsi, la surface saillante (15) scelle la partie saillante (21) du manchon (20).
