Abstract

L'invention concerne un élément d'assemblage d'angle (10), comprenant un corps de base (12) de forme cubique qui possède une surface fermée qui s'étend sur une première face du cube (14) et une deuxième (16) et une troisième surface fermée (18) qui s'étendent sur deux faces adjacentes entre elles et perpendiculaires à la première face du cube (14), tandis qu'un embout respectif de section extérieure prismatique, destiné à l'embrochage d'une extrémité d'un tube de section intérieure (32) adaptée à la section extérieure de l'embout part des faces du cube opposées à la deuxième et à la troisième face. Sur sa ligne de fuite (34), l'embout possède des éléments de retenue (36) dépassant élastiquement qui s'engagent dans un passage (38) formé par l'extrémité du tube et viennent en appui contre un bord (40) du passage afin de maintenir l'extrémité du tube (28, 30) en position axiale en appui contre la surface de paroi (20, 21). Selon l'invention, l'élément de retenue (36) est un coulisseau (48) mobile dans un conduit (44) disposé perpendiculairement à l'axe du tube (42) contre la force d'un ressort (46) qui, en position de travail, dépasse du conduit sous l'effet de la tension du ressort par deux surfaces obliques telles que l'une des surfaces obliques forme avec la direction de poussée du coulisseau (48) un premier grand angle (54) en tant que surface d'entrée (52) et l'autre surface oblique forme en conséquence un petit angle (56) en tant que surface de retenue (50).
