A system for tightly connecting two enclosures, comprising:
- a first tight device giving access to a first enclosure of the two enclosures, the first tight device comprising:
- a first flange, which delimits a through opening, defining a central axis, and which is adapted to be tightly attached to the first enclosure so as to connect interior and exterior of the first enclosure via the through opening;
- a first door that is movable relative to said first flange between a closed configuration, in which the first door closes the through opening, and an open configuration, in which the first door is clear of the through opening,
- a gasket, which is attached to said first flange and which seals closing of the through opening by said first door in the closed configuration;
- a tubular member, movably mounted on said first flange between:
- a retracted position in which the tubular member is arranged outside the through opening, the retracted position being occupied by the tubular member when said first door is in the closed configuration, and
- a deployed position in which the tubular member is arranged in the through opening so as to cover said gasket, the deployed position being occupied by the tubular member when said first door is in the open configuration;
- and
- an elastic member, adapted to drive said tubular member from the retracted position to the deployed position when said first door is in the open configuration,
- wherein said first flange and said first door are provided with first fastening means adapted to fasten said first flange and said first door together in a reversible manner in a closed configuration;
- and
- a second tight device giving access to a second enclosure of the two enclosures, comprising:
- a second flange, which is adapted to be tightly attached to the second enclosure so as to access interior of the second enclosure through the second flange;
- and
- a second door, carried by said second flange movably between a closed position, in which the second door tightly seals said second flange, and an open position, in which the second door is moved away from said second flange to access the second enclosure through said second flange,
- wherein (i) said first flange and said second flange are provided with second fastening means, adapted to reversibly fasten said first flange and said second flange to each other, and (ii) said first door and said second door are provided with third fastening means adapted to reversibly fasten said first door and said second door to each other, so that, when assembling said first flange and said second flange to connect the first and second enclosures by centering said first flange and said second flange on the central axis and by moving said first flange and said second flange relative to each other in rotation about the central axis, the second fastening means fixedly connects said first flange and said second flange to each other while, at the same time, the third fastening means fixedly connects said first door in the closed position and said second door in the closed configuration to each other and the first fastening means detaches said first door in the closed configuration from said first flange.
