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. The lower end of the locking member is constructed to engage the tool attachment when the locking member is positioned in an engaging position and to release the tool attachment when the locking member is moved to a release position. An actuating member is movably positioned on the drive stud, and the actuating member defines a sliding surface oriented transversely to the locking member to engage a ledge surface of the locking member. Movement of the actuating member along the longitudinal axis of the drive stud in a selected direction causes the ledge surface to slide along the sliding surface to move the locking member from the engaging to the release positions.
