1. A cryogenic tank for storing liquefied fluid, comprising an inner shell delimiting a storage volume for liquefied fluid and an outer shell arranged in a spaced manner around the inner shell, the space between said inner and outer shells comprising a thermal insulation, the inner and outer shells extending in a longitudinal direction between two longitudinal ends, the tank comprising a structure for holding the inner shell in the outer shell, the holding structure being composed of a first mechanical connection between a first longitudinal end of the inner shell and a first longitudinal end of the outer shell, and of a second mechanical connection between the second longitudinal end of the inner shell and the second longitudinal end of the outer shell, the first mechanical connection comprising a first support wall of general truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell, wherein the second mechanical connection comprises a second support wall of general truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell,
wherein the second support wall is inclined by an angle of between 60 degrees and 89 degrees with respect to the longitudinal direction.
