A device for closing an opening, particularly a man hole. The device includes a frame and a cover articulated to the frame around a first axis by a hinge. The device also includes a locking mechanism having a locked configuration, whereby the cover is held open in a first position, and an unlocked configuration, whereby the cover is disposed in a second position in which the cover can be pivoted around the first axis. The hinge is designed such that, while resting on the frame, the cover can pivot around a second horizontal axis. Moreover, the cover is pivoted around the second axis to move between the two positions. The device is suitable, e.g., for cast iron man holes.
