The invention relates to a device for transferring fluid between two separate structures including a rigid pipe with a double shell extending along a longitudinal axis, the pipe including an outer shell housing, in the inner vacuum space thereof, at least one inner duct for fluid transfer, the pipe including, at a first end, a first rigid connection of the outer shell to the first structure and, at a second end, a second rigid connection of the outer enclosure to the second structure, the first and second ends of the outer shell being rigidly connected to the at least one inner duct, the pipe comprising a system to compensate for movements, including at least one flexible area and at least one resilient area, in the longitudinal direction, the system to compensate for shifts also including a connection which slides along the longitudinal axis between the outer shell and the first structure and a gimbal mechanism comprising two gimbals and mechanically connecting the two ends of the flexible area.

A device for transfer of fluid between two ends which are designed to be connected respectively to two separate structures, the device comprising rigid double-envelope piping which extends according to a longitudinal axis, the piping comprising an outer envelope which accommodates in its inner volume which is designed to be put under vacuum at least one inner duct for transfer of fluid, the piping comprising at a first end a first rigid connection of the outer envelope to the first structure, and, at a second end, a second rigid connection of the outer envelope to the second structure, the first and second ends of the outer envelope being connected rigidly to the at least one inner duct, the piping comprising a system for compensation for relative displacements between its first and second ends, comprising at least one flexible area and at least one resilient area, said at least one resilient area being resilient according to the longitudinal direction, the system for compensation for displacements additionally comprising a connection which slides according to the longitudinal axis, between the outer envelope and the first structure, and a mechanism of universal joints, containing two universal joints and mechanically connecting the two ends of the flexible area.
