A dispensing head, intended for actuating a dispensing element mounted on a container and for dispensing a product contained in the container, includes: a) a mechanism for fastening the head to the container; b) a dispensing duct able to communicate with the product inside the container; and c) an actuating mechanism for actuating the dispensing element. The actuating mechanism can be provided with a dispensing orifice and is able to move with respect to the duct between a first position in which the product can be dispensed and a second position in which the product cannot be dispensed and in which the dispensing element cannot be actuated. The actuating mechanism is able, in the second position, to butt against an integral portion of the fastening mechanism that prevents displacement of the actuating mechanism from the first to the second position.
