Closing device for swing doors, characterized essentially by the fact that consists of a cylinder mounted on one side of the door, near the edge of articulation thereof and one of the adjacent edges, inside which is mounted a plunger pushed towards the outside by a spring, whose piston is equipped at its free end with a bearing that rests on a track arranged in arc, fixed to the door pillar, which forms two slopes that converge at a midpoint of the track, towards whose point tends to move the roller forcing the door to swing towards its closing position.
