Abstract

Cette invention se rapporte à un raccord servant à raccorder les parties terminales de tuyaux d'évacuation à paroi double, dont les parties de raccordement forment un joint universel, pour que les tuyaux d'évacuation puissent être raccordés en formant un coude selon un angle prédéterminé. Une partie support (2) comportant un espace interne sphérique est fixé à l'un (1) des tuyaux d'évacuation à raccorder. Une partie d'insertion sphérique (7) est fixée à l'autre tuyau d'évacuation (1') correspondant à un surface interne de la partie support. Ainsi, lorsque la partie d'insertion sphérique est introduite dans la partie support à raccorder, le tuyau d'évacuation est monté avec un coude par rapport à l'autre tuyau d'évacuation selon un angle prédéterminé.
