Abstract

L'invention concerne une structure où un raccord fractionné comprend un ensemble de segments fractionnaires solidarisés par un boulon et un écrou et est rendu solidaire d’une canalisation par la force de fixation du boulon et de l’écrou. La structure selon l’invention augmente la résistance de la jointure entre le raccord et la canalisation. Dans un raccord fractionné qui comprend un ensemble de segments fractionnaires solidarisés par un boulon et un écrou et est rendu solidaire d’une canalisation par la force de fixation du boulon et de l’écrou, un élément de bague est monté sur la surface périphérique extérieure d’un tronçon tubulaire du raccord solidaire de la canalisation. L’élément de bague présente un diamètre inférieur au diamètre extérieur du tronçon tubulaire au moins, de telle sorte que, lorsque l’élément de bague est monté en position, le diamètre extérieur du tronçon tubulaire est réduit.
