A positioning device for a hand-held setting tool (10) includes an actuating switching device having an actuation element (24), a switching link (30) for connecting an actuation element (24) to the actuation switch (13) of the setting tool (10) and having a switching member axially displaceable relative to a stationary, with respect to the holder, structural component. The device further includes a safety device (50) for preventing actuation of the actuation switch (13) at a predetermined orientation of the setting tool (10). The safety device (50) includes a displaceable blocking element (55), first and second annular recesses (51, 52) for receiving the blocking element and extending radially circumferentially about the structural component and about the switching member, respectively. The first (51) and the second (52) annular recesses are open toward the switching member and the structural component, respectively. The blocking element (55) is completely positionable in one of the first and second annular recesses (51) in an operational position of the actuation switching means.
