Abstract

Un tourniquet pour des parties du corps, en particulier ses extrémités, telles que l'avant-bras, comprend une courroie ou similaire introduite à travers un logement de blocage et formant une boucle lorsqu'une de ses extrémités est introduite dans le logement de blocage. Un levier de serrage pivotable est utilisé pour serrer de façon libérable la courroie dans le logement de blocage pendant la constriction d'une partie du corps. Le levier de blocage forme une éclisse d'insertion, est agencé à une extrémité de la courroie et est inséré et encliqueté dans le logement de blocage afin de serrer la courroie.
