Abstract: The invention relates to a closure device for man-door in overhead garage doors. The invention is suitable for garage doors (12) having a man-door (33) which opens into the garage. The invention includes a first supporting element (1, 1a, 45) in the garage door (12) for retaining a moving element (4, 4a, 4b) assisted by at least one spring (30, 37, 41), such that the moving element projects from the garage door (12) to the exterior of the garage. The moving element is connected to a pin (25, 25a) provided in a second supporting element (28, 45) secured to the garage door (12) opposite the man-door (33). In order to close the door (12), the moving element presses against a fixed zone (13) of the garage and maintains the pin (25, 25a) in a position in which the man-door (33) is open and, when the garage door (12) is opened, the pin (25, 25a) closes the man-door, thereby ensuring that the man-door closes when the garage door (12) opens.
