An air nozzle closure for a spray gun with an air cap, which has at least one axial borehole for the passage of exiting air and a first annular flange, which is radially directed outward, and an air nozzle ring surrounding the air cap, with a second annular flange radially directed inward, and an inside thread for the screwing on of the air nozzle closure with an outside thread of the spray gun. The air cap in the screwed state, with annular flanges adjacent to one another, is clamped in between the spray gun and the air nozzle ring, and a first annular groove with a locking ring, which secures the air nozzle ring in the unscrewed state against the loosening of the air cap. The locking ring has at least one elastic snap-in element projecting inward to snap into the annular groove.

1. Air nozzle closure for a spray gun with an air cap, which has at least one axial borehole for the passage of exiting air and a first annular flange, which is radially directed outward, and an air nozzle ring surrounding the air cap, with a second annular flange radially directed inward, and an inside thread for the screwing on of the air nozzle closure with an outside thread of the spray gun, wherein the air cap in the screwed state, with annular flanges adjacent to one another, is clamped in between the spray gun and the air nozzle ring, and a first annular groove with a locking ring, which secures the air nozzle ring in the unscrewed state against the loosening of the air cap, wherein the locking ring has at least one elastic snap-in means projecting inward to snap into the annular groove. 2. Air nozzle closure according to claim 1, wherein the locking ring is a continuous plastic ring. 3. Air nozzle closure according to claim 1, wherein the elastic snap-in means is at least one fastening lug projecting inward. 4. Air nozzle closure according to claim 3, wherein the fastening lug is a surrounding lug. 5. Air nozzle closure according to claim 3, wherein a plurality of fastening lugs are located at a distance from one another. 6. Air nozzle closure according to claim 1, wherein the width of the annular groove exceeds the thickness of the locking ring, wherein the locking ring can be moved axially within the annular groove, and the level of the locking ring is at least slightly greater than the depth of the annular groove. 7. Air nozzle closure according to claim 6, wherein the width of the annular groove exceeds the thickness of the locking ring by approximately 20%. 8. Air nozzle closure according to claim 5, wherein the level of the locking ring is approximately three times the depth of the annular groove. 9. Air nozzle closure according to claim 1, wherein the outside edge of the locking ring is designed axially enlarged in the direction of the air nozzle ring, and with this enlargement, is firmly connected with the air nozzle ring. 10. Air nozzle closure according to claim 1, wherein the outside edge of the locking ring in the range of the air nozzle ring has an additional extension pointing radially inward, and the air nozzle ring is connected with the locking ring in a tight fit. 11. Air nozzle closure according to claim 1, wherein the locking ring has a surface which is optically different from the surface of the air nozzle ring and the air cap.
