The invention relates to a dispensing head for an aerosol container provided with a valve. The dispensing head is made up of a cover (2) to which an actuating member (1) is secured, provided with a push button (11) which can be moved between a non-depressed rest position and a depressed actuating position. According to the invention, the actuating member (1) is provided with a blocking element (12) which can pivot between an unlocked position in which said element does not block the movement of the push button (11) relative to the cover (2) and a locked position in which said element blocks the push button in the rest position by preventing said push button from entering the actuating position.
