Abstract

Joint (10) de raccordement permettant de fixer un premier tuyau (12) à un deuxième tuyau. Le joint de raccordement comprend un corps annulaire (14) et une pluralité de logements (18) pour clavettes qui s'étendent depuis le corps annulaire (14) et se caractérisent par des faces arrières ouvertes (38) qui permettent d'effectuer un moulage sans noyau. Un boulon (32) est introduit dans un trou (30) prévu dans chaque logement (18) de clavette et une clavette (40) est placée dans chaque logement (18) associé. Chaque clavette (40) comporte une dent (52) actionnée par le boulon, une dent (54), plus grosse, actionnée par la pression, une surface supérieure (44) comprenant une encoche (48) prévue pour loger coulissant un actionneur (32) de boulon et une surface inférieure qui est partiellement réduite pour servir de palier (76) limitant l'ampleur de l'action du boulon.
