A tool of the type having a drive stud for receiving and releasing a tool attachment includes an opening in the drive stud and a locking pin movably mounted in the opening. The opening defines upper and lower ends, and the lower end of the opening is located at a portion of the drive stud constructed for insertion into the tool attachment. An actuating member is movably positioned on the drive stud, and the actuating member defines a sliding surface oriented transversely to the pin to engage an upper end of the pin. A first spring biases the sliding surface toward the pin, and a second, weaker spring biases the pin toward the sliding surface. Movement of the actuating member along the longitudinal axis of the drive stud in a selected direction allows the second spring to slide the pin from the engaging to the release positions.

Clé à cliquet avec carré entraîneur comportant une ouverture logeant un axe de verrouillage mobile commandé par un ressort. L'ouverture définit une extrémité supérieure et une extrémité inférieure qui est positionnée en une portion du carré entraîneur destinée à l'insertion dans les douilles. Un dispositif coulissant permet de commander le déplacement de l'axe de verrouillage. Un premier ressort pousse la surface coulissante vers l'axe, et un deuxième ressort, moins puissant, chasse l'axe de verrouillage vers la surface coulissante. Le coulissement du dispositif de commande le long de l'axe longitudinal du carré entraîneur dans une autre direction donnée permet au deuxième ressort de libérer l'axe de la position de verrouillage.
