The present invention relates to a headlight apparatus in which fastening of an occulter is independent from the fastening of a light source. To this end, the headlight apparatus includes an occulter with an occulting portion which is fitted in a reflector, the occulting portion being extended in length by a central portion which is terminated by a retaining foot held in a housing formed on an outer face of the reflector, at the level of an aperture formed in the body of the reflector, by mechanical pressure exerted between the walls of the housing and the retaining foot. Preferably, the retaining foot consists of a first tongue which is used as a locking key, and a second tongue which includes, in particular, a locking slot for receiving the locking key whereby to spread the retaining foot laterally.

What is claimed is: 1. A headlight apparatus for a motor vehicle, comprising: (a) a light source; (b) a reflector element within which the light source is disposed, the reflector comprising a concave inner face having a first aperture; and (c) an occulting element that comprises an occulting portion located within the reflector for intercepting light signals emitted by the light source, a central portion and a retaining foot, the retaining foot being held, in a housing formed on an outer face of the reflector at the level of the first aperture, by mechanical pressure exerted between walls of the housing and the retaining foot, wherein the retaining foot of the occulting element comprises a first tongue which is used as a locking key, and a second foot which includes, a locking slot for receiving the locking key. 2. The headlight apparatus according to claim 1, wherein the occulting element is a component made in one piece. 3. The headlight apparatus according to claim 1, wherein the first aperture comprises a circular portion and a slot portion, the housing being formed facing the slot portion of the first aperture. 4. The headlight apparatus according to claim 1, wherein the housing comprises a lower portion having a second aperture through which the central portion of the occulting element extends. 5. The headlight apparatus according to claim 4, wherein the second tongue comprises at least one fastening lug, each fastening lug being bent back on a lower face of the housing, which prolongs the inner face of the reflector, whereby to secure the occulting element against axial movement on the reflector. 6. The headlight apparatus according to claim 5, wherein the second fastening tongue comprises a first fastening lug and a second fastening lug. 7. The headlight apparatus according to claim 6, wherein the first fastening lug and second fastening lug are disposed on either side of the central portion of the occulting element, the first fastening lug and second fastening lug meeting together at the level of a base portion of the second fastening tongue, which is placed in abutment against a flat portion of the second tongue whereby to maintain the locking key in a horizontal position. 8. The headlight apparatus according to claim 1, wherein the occulting element is made from a material comprising layers of aluminum and milled steel laminated together. 9. The headlight apparatus according to claim 1, wherein the central portion of the occulting element comprises a first flank and a second flank, at least one of the flanks having a return portion for stiffening the central portion. 10. The headlight apparatus according to claim 9, wherein the first flank and second flank are secured together by fastening means. 11. A motor vehicle equipped with headlight apparatus according to claim 1. 12. A method of fastening an occulting element on a headlight apparatus, the headlight apparatus comprising a light source and a reflector element comprising a concave inner face having a first aperture, comprising the of: (a) forming, on an outer face of the reflector at the level of the first aperture, a housing for receiving the occulting element; (b) installing the occulting element within the headlight apparatus, the occulting element comprising an occulting portion, a central portion and a retaining foot having a first tongue defining a locking key and a second tongue defining a locking slot; and (c) inserting the locking key into the locking slot, so as to cause the retaining foot to spread laterally and provide mechanical pressure between walls of the housing and the retaining foot to prevent movement of the occulting element. 13. A method according to claim 12, which includes the step, in the course of the step of inserting the locking key into the locking slot, of bending back at least one fastening lug situated at one end of the second tongue, on a lower face of the housing which extends in length an inner face of the reflector, whereby to prevent axial movement of the occulting element. 14. A method according to claim 12, which includes, before the step of installing the occulting element within the headlight apparatus, the step of positioning the retaining foot in facing relationship with the housing, by passing the retaining foot through the first aperture formed in the body of the reflector. 15. A method according to claim 12, which includes, before the step of installing the occulting element in the headlight apparatus, the step of positioning the retaining foot in facing relationship with the housing by passing the occulting portion through the first aperture formed in the body of the reflector.
