1. Sealing test device for testing sealing of at least a part of a double-door sealed transfer system between two closed volumes, said system comprising first and second flanges capable of being rigidly connected to one another, and first and second doors normally sealing openings respectively defined by the first and the second flanges, the seal-testing device being configured to separately test the sealing between the first flange and the first door and between the second flange and the second door, said device including a casing comprising a cavity provided with an opening, means for mechanical connection to at least one of the first and second flanges so that the cavity is closed by one of the first and second flanges and one of the first and second doors, and an inflatable joint intended to come, in the inflated state, in contact with one of the first and second flanges and to ensure a sealing allowing to verify the sealing between the first flange and the first door or the second flange and the second door.
