Abstract: A double-walled tank comprising at least one connection system connecting the outer and inner enclosures and enabling them to move in relation to one another in at least a longitudinal direction parallel to an axis of displacement when in operation. The connection system has an annular linear connection between a first contact surface rigidly connected to the outer enclosure and a second contact surface rigidly connected the inner enclosure, the first and second contact surfaces arranged opposite one another and configured to be in contact with one another along a contact circle that has a center positioned on the axis of displacement.
