A device for transferring fluid between two separate structures includes a rigid pipe with a double shell extending along a longitudinal axis. The pipe includes an outer-shell housing (in the inner vacuum space thereof), at least one inner duct for fluid transfer, and at first and second ends thereof, includes respective first and second rigid connections of the outer shell to the first structure and second structures, respectively. The first and second ends of the outer shell are rigidly connected to the at least one inner duct. The pipe comprises a system to compensate for movements in the longitudinal direction.
