Abstract: A device (1) for connecting a fixed turbine engine portion (2) and a distributor (3) foot (31) of a turbine engine turbine, comprising: a ring-shaped body (11) adapted so as to be connected and secured to the fixed turbine engine portion (2), and two ring-shaped upstream (12) and downstream (13) brackets secured to the body (11), both brackets (12, 13) being adapted so as to clamp the foot (31) of the distributor, characterized in that at least one bracket (12, 13) is interrupted by forming an expansion or retraction slot (121, 131), the slot (121, 131) allowing an expansion of the bracket (12, 13) tending to close the slot (121, 131) or retraction of the bracket (12, 13) tending to further open the slot (121, 131), under the effect of a difference in internal temperatures of the device.

Abstract: The invention relates to an assembly which includes: two rotationally symmetrical components (10, 20) for supporting the blades of a turbine engine, arranged one inside the other concentrically about a turbine engine axis, and a system (30) for locking the components (10, 20) such as to prevent the relative translation of same in the axial and radial directions relative to said axis, the system including a slotted ring (40) comprising a U-shaped cross-section suitable for receiving one end of the components (10, 20), the assembly being characterised in that the ring (40) and one of the components (10, 20) are shaped such as to allow the ring to be interlocked on the component, and in that the locking system (30) also includes a member for stopping the rotation of the ring relative to the component with which the latter is interlocked. The invention further relates to a method for assembling such an assembly.
