Le dispositif d'attache rapide selon l'invention permet d'éviter ces inconvénients, il comporte quatre éléments: une tête pouvant tourner et être poussée axialement dans un logement formant douille, la douille étant fixée sur un des éléments amovibles dont on veut assurer la fixation par rapport à l'autre, une embase de retenue élastique fixée sur le second élément. A l'extrèmité opposée de la tête, la cheville est conique et comporte deux encoches prévuées pour venir s'engager dans deux 'pattes  The quick coupling device according to the invention makes it possible to avoid these drawbacks, it comprises four elements: a head that can rotate and be pushed axially into a socket housing, the sleeve being fixed on one of the removable elements which one wants to ensure the fastening relative to each other, an elastic retaining base attached to the second element. At the opposite end of the head, the ankle is conical and has two notches provided to engage in two 'legs
