Abstract
A link device between an enclosure for passing cooling air and a stator nozzle in a turbomachine, the device comprising metal tubes having their ends mounted in leaktight manner in orifices in a casing and in orifices in the stator nozzle, one end of each tube being engaged in a ring having an outer collar movable in sliding between two surfaces carried by the nozzle, the guide surface situated beside the casing being held stationary relative to the nozzle, while the other guide surface is movable axially relative to the nozzle and is associated with return means urging it towards the casing.
