Device for sealed connection between two containment enclosures for improved sealing

A device for a sealed connection between a first enclosure and a second enclosure, said first enclosure comprising a first opening and said second enclosures comprising a second opening, said device comprising:

• a first door provided with a first coaxial complementary flange intended for delimiting said first opening of said enclosure,
• a second door provided with a second coaxial complementary flange intended for delimiting said second opening of said second enclosure,
• a first peripheral seal assembled with the first door and arranged between the first door and the first flange when the first door is closed off on the first flange,
• a second peripheral seal assembled with the second flange and arranged between the second door and the second flange when the second door is closed off on the second flange,
• wherein said first peripheral seal comprises a first annular seal body extended in the inner peripheral portion thereof by a first annular bead, said first annular seal body and said first annular bead defining an inner peripheral face forming a shoulder,
• wherein said second peripheral seal comprises a second annular seal body extended in the outer peripheral portion thereof by a second annular bead, said second annular seal body and said second annular bead defining an outer peripheral face forming a shoulder,
• wherein the first door comprises a tubular bearing surface that is complementary to the inner peripheral face of the first annular seal body of said first peripheral seal on the one hand and a circular groove in which the first annular bead of said first peripheral seal is engaged on the other hand,
• wherein the second flange comprises a tubular bearing surface that is complementary to the outer peripheral face of the second annular seal body of said second peripheral seal on the one hand and a circular groove in which the second annular bead of said second peripheral seal is engaged on the other hand,
• wherein the first annular seal body of the first peripheral seal comprises at least one non-smooth face which is in contact with said first flange and/or said second door,
• wherein the second annular seal body of the second peripheral seal comprises at least one non-smooth face which is in contact with said second flange and/or said first door.
