The invention relates to a seal (10) inserted between two elements (4′, 6) having different coefficients of thermal expansion, said seal comprising: a first and a second metallic contact portion (16a, 16b) spaced along an axial stacking direction (8) orthogonal with respect to a radial direction (20); tight connection means (14) between the portions (16a, 16b), allowing a relative movement between same along a radial direction; and a first and a second sliding part (24a, 24b) respectively coupled in translation along the radial direction with the portions (16a, 16b), and stacked so as to be able to slide in relation to each other along the radial direction.
