Abstract

Ecrou d'assemblage en matière plastique destiné à être monté dans la boutonnière d'un premier élément sur lequel doit se fixer un second élément, par l'intermédiaire d'une vis qui le traverse par un trou adapté à son diamètre. L'écrou plastique conforme à l'invention se caractérise essentiellement par le fait qu'il est constitué d'un corps creux de forme oblongue muni sur ses parois longitudinales internes de saillies verticales parallèles déterminant entre elles une série de logements dans l'un desquels vient se loger la pointe de la vis de fixation du second élement, laquelle vis, au fur et à mesure de sa pénétration, vient s'y ancrer par déformation progressive desdites saillies et de la partie interne du corps de l'écrou. L'invention s'applique aux dispositifs d'assemblage en général.
