Abstract

Dispositif de sécurité comprenant une coiffe protectrice pour raccords vissés ou rapides. Les flancs porteurs du filetage extérieur 20 de la pièce filetée 7 et du taraudage 12 de la coiffe protectrice 9 presentent un plus grand angle de flanc beta qu'un filetage normal et la pièce filetée 7 présente un trou 28 dans la paroi duquel se trouve une gorge annulaire 27 pour recevoir une bague d'étanchéité ou d'assujettissement en rotation 29, la valve 31 montée mobile sur un ressort de compression 30 présentant à son extrémité supérieure un évidement en forme de fente 32. L'invention est applicable à l'établissement de raccordement d'essai ou de mesure sur des systèmes hydrauliques ou pneumatiques.
