1. A method of fabricating a device for ejecting a liquid or paste product, wherein the method comprises the following steps in order: aspiration of a product to be ejected into a volume of a container-holder of the ejection device using a puller member acting on a piston in the container-holder;dem
1. A method of fabricating a device for ejecting a liquid or paste product, wherein the method comprises the following steps in order: aspiration of a product to be ejected into a volume of a container-holder of the ejection device using a puller member acting on a piston in the container-holder;demounting the puller member from the container-holder;removal of the puller member from the device for ejecting the liquid or paste product;assembling a lever onto a rear body, the rear body having a rear opening and a leaf spring,wherein the lever incorporates a forwardly extending horizontal upper part and a lower end in the form of an axle;inserting the axle into the rear body along an axis of the rear body, the leaf spring of the rear body deforming to receive the axle;assembling the rear body to the container-holder; andinserting a rack through the rear opening until the rack causes the leaf spring to lock the axle along the axis and reaches a position in which a front face of the rack acts on the piston enabling ejection of the product from the volume. 2. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 1, wherein the method comprises a preliminary step of fixing a tool to the front end of the container-holder. 3. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 1, wherein the method comprises a preliminary step of assembling with the container-holder a syringe type device having an elongate cylindrical body delimited in its rear part by a piston mobile in longitudinal translation and comprising in its front part a needle retained by an end-piece. 4. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 1, wherein the step of assembling the rear body and the container-holder is effected by clipping at least two lateral blades of a first element extending longitudinally and having an outwardly oriented protuberance intended to cooperate with corresponding openings on the second element. 5. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 1, wherein the method comprises at least three steps of injection molding plastic material to form three separate parts of the device: the lever integrating a pawl, the container-holder and the rear body. 6. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 1, wherein the assembly of the rear body onto the container-holder comprises a connection between ejection means of the rear body and the piston of the container-holder so that the product may be ejected from the container-holder by action on these ejection means of the rear body. 7. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 1, wherein the method comprises a preliminary step of assembling the puller member directly or indirectly with the piston of the container-holder of the ejection device closing the volume to be filled. 8. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 7, wherein the connection between the puller member and the piston of the container-holder is effected by screwing the end of the puller member into the piston. 9. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 7, wherein the puller member used to aspirate the product is not part of the injection device, wherein the puller member comprises a threaded part configured to cooperate with a threaded part in the piston comprises. 10. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 2, wherein the anterior end of the container-holder has a shape globally inclined relative to the body but having a surface having at least one generatrix substantially parallel to the axis of this body in order to enable straight insertion of a needle type tool in this direction before bending it and fixing it in an inclined working position. 11. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 4, wherein the step of assembling the rear body and the container-holder is quasi-irreversible. 12. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 11, wherein the rack is adapted to move in a certain direction to cause ejection of the product, and movement of the rack in the opposite direction is prevented to prevent refilling of the device. 13. The method of fabricating a device for ejecting a liquid or paste product as claimed in claim 5, wherein the method comprises a fourth step of injection molding plastic material to form the rack. 14. A kit for fabricating a device for ejecting a liquid or paste product, comprising: a container-holder, a rear body having a rear opening and a leaf spring, and a demountable puller member, a rack that moves along the rear opening inside the rear body, and a lever incorporating a pawl for acting on the rack and an axle rotatable about an axis of the rear body, whereinthe container holder is configured to allow aspiration of a product into a volume of the container-holder using a puller member;the demountable puller member is configured to demount from the container-holder after aspiration, wherein the puller member used to aspirate the product is not part of the injection device;the lever is configured to be assembled to the rear body with the leaf spring forming a portion of the axis and being deformable to receive the axle, wherein the rack when inserted in the rear opening causes the leaf spring to lock the axle;the rear body is configured to be assembled to the container-holder to form an ejection device. 15. The kit as claimed in claim 14 for fabricating a device for ejecting a liquid or paste product, wherein the puller member is separate from the container-holder and has a connecting member for its direct or indirect connection to a piston of the container-holder. 16. The kit for fabricating a device for ejecting a liquid or paste product as claimed in claim 14, wherein the kit further comprises a tool-holder and a needle type tool both adapted to be connected to the container-holder.
