In the housing of a setting device for driving fastening elements, a belt-like magazine holding fastening elements in spaced relation is moved through a guide channel transversely of the path of a driving piston. A transport device positioned in the housing moves the magazine through the guide channel in a step-wise manner. A stop lever is pivotally mounted in the housing and is spring-biased at one end into the guide channel. When the magazine is located within the guide channel in the path of the stop lever, the transport device can be operated to move the magazine. When the magazine is moved out of the path of the stop lever, however, the stop lever extends further through the guide channel and its other end engages a pawl on the transport device blocking its operation so that the magazine cannot be moved through the guide channel.
