A stapling device (1) with at least two stapling heads (4, 5) attached to a stapling head unit (2) for stapling sheet-like material, in particular paper, cardboard or the like, is provided, wherein the distance between at least two stapling heads (4, 5) can be adjusted relative to each other. In a stapling device (1) according to the invention, the retrofitting necessary for various products is to be simplified. This is achieved in the invention by moveably arranging the stapling heads (4, 5) relative to each other, and providing a drive unit (9, 10) for setting the stapling head distance.
