1. A sliding joint assembly comprising a first part and a second part that have different expansion coefficients and that are subject to large mechanical and thermal stresses, the assembly including at least one substantially radial contact interface which is located between the first and second parts, a sealing gasket disposed at said contact interface, mechanical fastening means between the first and second parts, and a plurality of radially acting spring blades each having first and second ends, said spring blades being connected firstly via said first ends thereof to the first part only in a vicinity of said contact interface, and secondly via said second ends thereof to the second part only in a zone that is axially remote from said contact interface, said contact interface constituting a sliding contact surface between the first and second parts, while the second ends of the spring blades are connected to the second part via said mechanical fastening means constituted by detachable screw-and-nut type assemblies provided with spring washers for damping forces exerted in an axial direction which is substantially perpendicular to said radial contact interface.
