A locking device for drawers of a cabinet, including a case body, several drawers vertically arranged in the interior space of the case body, a slide seat disposed in the case body, a latch plate disposed on each drawer and a detent unit. One end of the latch plate is bent toward the drawer to form a stop section with a predetermined length and inclination angle. The detent unit includes an engaging body and a link. The engaging body is vertically slidably fitted in the slide seat. The engaging body is formed with several engaging holes corresponding to the latch plates of the drawers. An upper end of the engaging body is formed with an elongated hanging slot. The link is perpendicularly passed through the hanging slot to abut against the inner edge of the upper end of the hanging slot.
