Device for connecting a fixed portion of a turbine engine and a distributor foot of a turbine engine turbine

A device for connecting a fixed turbine engine portion and a distributor foot of a turbine engine turbine, comprising:

• a ring-shaped body adapted so as to be connected and secured to the fixed turbine engine portion,
• two ring-shaped upstream and downstream brackets secured to the body, both brackets being adapted so as to clamp the foot of the distributor, and
• an annular downstream overlapping metal sheet secured to the body and positioned downstream from the brackets, the downstream overlapping metal sheet being laid out so as to limit heating-up of a downstream chamber by a fluid from a vein located above the downstream chamber, the downstream chamber being positioned under and downstream from the foot of the distributor,
• wherein the downstream overlapping metal sheet is interrupted by forming an expansion or retraction slot, the slot allowing expansion of the downstream overlapping metal sheet tending to close the slot or retraction of the downstream overlapping metal sheet tending to further open the slot under the effect of a difference in internal temperatures of the device.
