The device comprises, in positions adjacent to the bearing surface (15) of the transportable container (1) on the fixed structure, a first member (16) for plugging the central channel (3) of the container (1), and a second member (17) for plugging the upper end of the well (18). These members are arranged inside a zone of contact of at least one o-ring seal (13) with the bearing surface (15). Each of the plugging members (16, 17) comprises a planar surface arranged, in its closing position, in the planar bearing surface (15) of the container or in the planar bearing surface of the fixed structure, respectively. At least one of the plugging members (16, 17) can move in the axial direction of the well (18) and of the central channel (3) of the container (1) and in a transverse direction perpendicular to the axial direction, between its closing position and its opening position.
