Claim 0:
1. A tight device giving access to an enclosure, comprising:
a flange, which delimits a through opening, defining a central axis, and which is adapted to be tightly attached to the enclosure so as to connect interior and exterior of the enclosure via the through opening;
a door that is movable relative to said flange between a closed configuration, in which the door closes the through opening, and an open configuration, in which the door is clear of the through opening;
a gasket, which is attached to said flange and which seals closing of the through opening by said door in the closed configuration;
a tubular member, movably mounted on said 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 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 and physically protect said gasket, the deployed position being occupied by the tubular member when said 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 door is in the open configuration.
