The invention relates to a ring installation pistol (1), which is used to automatically install orthodontic rings made of elastic material, which are molded onto a strip (7). By pulling the trigger (2), which is installed in a pistol-shaped housing (3), the working piston (4) is pressed forward. There, the wire fork tips (5), which have been moved toward each other, reach into one of the molded-on rings (6) and remove said ring from the strip of the ring by pulling the ring. At the same time, the magazine (8) moves to the side. The ring separated in such a way is then expanded by the spreading of the forks and pushed off onto a metal lock. When the trigger is returned, a gear (10) in the magazine is actuated by means of a transport lever (9), which gear moves the strip by means of a transport wheel (11) in such a way that the next ring on the strip can be grabbed in the following operation.
