Abstract

Système de raccordement d'une paire de conduits de fluide. Le système comprend un premier raccord présentant un corps (22) ayant un passage (24) à travers lequel est transporté un fluide, une ouverture à une extrémité du passage, et une languette (118) s'étendant à partir du premier corps (112) du raccord près de son ouverture. La languette (118) présente une taille et une forme prédéterminées pour correspondre de façon unique à un fluide particulier choisi dans un groupe de fluides pour lesquels le système est conçu. Le système comprend également un second raccord présentant un corps ayant un passage à travers lequel est transporté un fluide, une ouverture à une extrémité du passage et un rainurage dans le second corps du raccord adjacent à son ouverture. Le rainurage (32) présente une taille et une forme présélectionnées pour recevoir la languette du premier connecteur de manière que ladite languette (118) puisse être insérée dans le rainurage (32) lors du raccordement des premier et second raccords. La taille et la forme du rainurage (32) sont sélectionnées pour empêcher l'insertion dans le rainurage de languettes (118) ayant des tailles et des formes correspondantes à des fluides d'un groupe autre que celui du fluide particulier.
