ABSTRACT:
A sealing device disposed between two turbomachine elements traversed by gases, particularly between a combustion chamber and a high pressure turbine nozzle support. The device includes an independent collar supported by first and second bearing surfaces on the elements which are to be connected in leaktight manner, the collar being constructed of a material having a thermal expansion coefficient which is different from that of the elements which it interconnects so as to ensure a leaktight connection between the elements.
