Zusammenfassung:A safety cap (10) for a motor vehicle fluid reservoir (14), the cap configured to be attached and fixed to a neck (12) of the reservoir. The cap includes a screwing cover (16) with a first screw thread (16ba), and a safety cell (18) configured to allow the passage of gas from the interior to the exterior of the reservoir, and/or vice versa, when the cap is fixed to the neck and when a pressure difference between the interior and the exterior of the reservoir is greater or less than at least one predetermined threshold value. The cap includes a ring (20) with structure (30, 30a, 32) for fixing to the neck and a second screw thread (22) to cooperate with the first screw thread, the cell at least partly housed in the neck and surrounded by the cover and/or the ring when the cap is fixed on the neck.
