• the locking element 40 according to the first embodiment, comprises an open ring 45 elastically deformable to be assembled around the head 20.
• Figure 5 shows the open ring 45 before mounting on the head 20.
• the open ring 45 comprises in this example two locking projections 41, and each end edge 44 of the ring may be provided with a breakable element 42, serving as first-use control. The two projections and the two breakable elements project towards the inside of the open ring 45.
• the ring 45 extends at least partially around the actuating head 20, as shown schematically on the FIG. 6.
• the actuating head has on its lateral wall four openings 21, two of which receive said projections of blocking 41 in the locking position and the other two receive said breakable elements 42 in the locked position, before the first use. It is understood that the invention is not limited by the example shown in the drawings and it is possible to envisage a different number of locking projections and / or breakable elements as well as corresponding openings of the actuating head.
• the locking element in the locked position, cooperates via its locking projections 41, both with an upper surface or a flange 31 of the fixing ring 30 (FIG. or an element integral therewith) and the openings 21 of the actuating head 20, to prevent axial displacement of the head 20 with respect to the ring 30.
• the locking projections 41 extend from the ring of the open ring 45, through the openings 21 of the head, on the flange 31 of the fixing ring 30, perpendicular to the axis of sliding between the head 20 and the fixing ring 30.
• the two breakable elements 42 located at each end edge 44 of the ring, are adapted to break or warp.
• these breakable elements may be formed by two tongues 42. These tongues cooperate with the edge of the openings 21 of the head, so as to be separated, in this example, from the locking element , under the effect of the disengagement of the blocking element 40 by the user.
• the presence of intact tabs 42 thus guarantees the user that the locking element has never been moved out of its locking position. Thus it is certain that the device has never been activated.
• the open ring 45 can be replaced in the locked position.
• the user can snap the open ring around the actuating head 20.
• the snapping can be facilitated by the shape of the edges of the two ends 44.
• the two end edges 44 brought into contact with the actuating head 20, are substantially tangent with respect to the circular wall of the head, to allow sliding engagement, easier, the ends of the ring around the head until snapping.
• the shape of the edges of the ends of the ring also has the advantage of not damaging the actuating head during successive snaps and disengages.
• the open ring thus extends again at least partially around the actuating head, each locking projection 41 cooperating with the fixing ring or an element secured thereto, through one of the openings 21. of the actuating head, to prevent actuation of the pump.
• the locking element is made of plastic material both resistant to allow the locking element to be reusable, and deformable to allow snapping and disengagement of the locking element.
• Other materials are also possible.
• the four openings 21 of the actuating head shown in the figures are distributed symmetrically about the longitudinal axis of the dispensing member, in this case the pump in the example shown.
• the two locking projections 41 and the two tabs 42 adapted to cooperate with the four openings of the actuating head are advantageously also positioned symmetrically on the ring open relative to the center of the ring.
• the locking element 40 according to the invention can thus be engaged on the actuating head by any side.
• This embodiment allows simple and fast assembly because it does not require to orient each actuating head, when mounting the locking element on the head. Similarly, for the user, the replacement of the locking element can be done very easily after each use. Simply snap the ring, if necessary, by rotating it slightly around the head, until each projection lock can be inserted into any of the openings of the actuating head.
• the locking element comprises two substantially parallel branches 41 ', which constitute two locking projections.
• the locking element has a U-shape, as can be seen in FIGS. 7 to 9.
• the transverse wall 46 ' which connects the two parallel branches 41' of the locking element may protrude on either side of the base branches, to form the gripping means 43 '.
• the free ends of the branches 44 'each comprise a breakable element 42' formed by a tongue in the example shown.
• the actuating head 20 has four openings 21, which can be arranged symmetrically about the longitudinal axis of the head.
• each branch 41 ' when assembled in the blocking position, penetrates inside the head 20 by a first opening 21, passes through the space between the dispensing member 10 and the inner wall of the head, and spring out of the head by a second opening 21.
• each branch thus cooperates both with two openings of the actuating head and the edge 31 of the fixing ring 30 or an integral element of this one, perpendicular to the axis of actuation.
• each breakable element cooperates with the edge of an opening.
• the tabs 42 ' are retained outside the actuating head by the edge of said respective second openings 21 against which they break.

• the U-shaped locking element can be easily engaged by two openings of the head, by sliding the branches on the flange 31 of the fixing ring 30.
• the locking element may not come out of the head by the second openings.
• the locking element is held in the locking position by retaining means to prevent the locking element from disengaging very easily from the actuating head.

• These retaining means may also comprise, as represented in FIG. 9, at least a retention projection 45 'located on a locking projection 41'.
• FIG. 9 shows two retaining projections 45 'forming two symmetrical shoulders on the two respective locking projections 41 '.
• Each retaining projection cooperates with the inner wall of the actuating head 20 by creating a kind of latching and prevents the exit of the locking element from the actuating head.
• the user To remove the locking member, the user must exert a threshold pull force which overcomes said retaining projections.
• the locking element thanks to these retaining means, remains in the locking position, which allows the dispensing device to be transported safely, without the risk of being actuated inadvertently.
• the blocking element of the present invention applies to all existing fluid dispensing devices, without any other modification of the device than the creation of holes in the actuating head. .
