Abstract

L'invention concerne une clé à cliquet (10) comprenant un boîtier (12), à une première extrémité duquel se trouve un évidement (14) en forme de segment de cercle dans lequel est accueilli un insert rotatif qui peut tourner, lequel possède une partie de guidage (18) en forme de segment de cercle dotée d'une ouverture (20) en forme de fourche, ainsi que deux éléments formant griffes (22, 23) maintenus pivotants l'un vers l'autre à des côtés mutuellement opposés de la partie de guidage (18) et qui, dans une position fermée, reposent l'un contre l'autre par deux extrémités extérieures (32, 34) et entourent, conjointement avec la partie de guidage, un évidement hexagonal sous la forme d'une vis (26). Les deux éléments formant griffes (22, 23) peuvent être pivotés vers l'extérieur avec leurs extrémités extérieures (32, 34) depuis une position initiale dans une position ouverte, de sorte que la clé à cliquet (10) peut être montée sur une vis (26) et poussée contre celle-ci de manière à ce que la vis (26), lors de la poussée, est guidée dans l'ouverture en forme de fourche (20) de la partie de guidage (18) et vient en butée contre des surfaces de commande (36, 38) arrière des éléments formant griffes (22, 23) afin de pivoter les éléments formant griffes dans une position fermée, dans laquelle la vis (26) est entourée par les éléments formant griffes (22, 23) et la partie de guidage (18) et l'insert rotatif peut tourner à l'intérieur de l'évidement (14). La partie de guidage (18) et les deux éléments formant griffes (22, 23) possèdent au niveau de leur pourtour extérieur une denture extérieure (29) périphérique qui coopère avec une partie de cliquet afin de permettre un serrage de la vis (26) dans une première position d'encliquetage et un desserrage de la vis (26) dans une deuxième position d'encliquetage.
