Abstract

L'invention concerne un dispositif de fixation (20) destiné à une entretoise diagonale (10) sur une première perche verticale (12). Le dispositif de fixation (20) peut être fixé à la première perche verticale (12), par l'intermédiaire d'une protubérance (40), à savoir par complémentarité de forme à un évidement (42) de la perche se présentant notamment sous la forme d'un évidement de passage. L'entretoise diagonale peut être fixée à un raccord diagonal (38) du dispositif de fixation (20). Le raccord diagonal (38) est, de préférence, relié directement à la protubérance (40). Le dispositif de fixation (20) présente également un raccord vertical (36) qui est relié au raccord diagonal 38. Le raccord vertical (36) permet d'immobiliser la protubérance (40) contre tout retrait de l'évidement (42) de la perche.
