Patent

CA 2306551

The invention relates to a device for connecting two rigid tubular objects, comprising a male part and a female part. The male part is provided with at least one transverse edge in its outer wall. A sleeve-shaped element is arranged to be placed between said parts when inserting the male part into the female part, said element being provided with at least one resilient tongue with a first member which is arranged to resiliently engage the recess of the female part when inserting the element into the female part, and a second member which is arranged to resiliently snap into place behind the transverse edge of the male part when inserting the male part into the element. The resilient tongue allows the female part and the male part to be separated by turning the element relative to the male part to a position where the second member of the resilient tongue is arranged laterally of the transverse edge of the male part and/or by moving the first member of the resilient tongue out of engagement with the recess of the female part.

L'invention concerne un dispositif servant à relier deux objets tubulaires rigides, comportant une partie mâle (6) et une partie femelle (1). La partie mâle (6) possède au moins un bord transversal (8, 9) dans sa paroi extérieure. Un élément en forme de manche (11) est placé entre lesdites parties lors de l'insertion de la partie mâle dans la partie femelle. Ledit élément comprend au moins une languette résiliente (12, 13) pourvue d'un premier élément (14, 15) placé de façon à s'adapter d'une manière résiliente dans l'encoche (3, 4) de la partie femelle lors de l'insertion de l'élément dans la partie femelle, et d'un second élément (16, 17) conçu pour se mettre en place par encliquetage de manière résiliente derrière le bord transversal de la partie mâle lors de l'insertion de la partie mâle dans l'élément. La languette résiliente permet de séparer la partie femelle de la partie mâle en tournant l'élément de la partie mâle vers une position, dans laquelle le second élément de la languette résiliente est placé latéralement par rapport au bord transversal de la partie mâle, et/ou en dégageant le premier élément de la languette résiliente hors de l'encoche de la partie femelle.
