Abstract

L'invention concerne un dispositif permettant de vérifier l'étanchéité d'une fermeture ou d'une soudure de raccordement dont est doté un tuyau flexible rempli de fluide. Le dispositif comprend deux éléments de serrage coulissant l'un par rapport à l'autre de manière à former en position insérée une section constituée d'au moins un espace de serrage et un espace de détente, ainsi que d'un moyen de pliage. Le dispositif est conçu de manière à ce qu'au moins une partie du tuyau puisse se plier et se verrouiller dans au moins un espace de serrage afin que le fluide présent dans au moins une partie du tuyau soit pressée contre une autre partie du tuyau comprenant la fermeture ou la soudure de raccordement à vérifier, alors que l'autre partie du tuyau peut se détendre dans l'espace de détente.
