An ejection device for a flight data recorder includes an ejection spindle, which can be detachably connected to the flight data recorder by means of a bayonet coupling. The bayonet coupling can be released by means of force application by the ejection spindle, a disengaging device, which has a compression-resistant housing and into which the ejection spindle can be screwed, and a gas pressure generator, a valve, which is located within the disengaging device and which permits a flow connection between the outlet of the gas pressure generator and the ejection spindle when the ejection spindle is screwed in and which disables the flow connection between the outlet of the gas pressure generator and the ejection spindle when the ejection spindle is unscrewed.
