1. A turbomachine subassembly comprising:
a first component forming a combustion chamber wall portion of the turbomachine; and
a second component forming a member for connecting the first component to a structural element of the combustion chamber,
wherein the first component and the second component are made of materials having different coefficients of expansion,
wherein the first component and the second component are axisymmetric elements coaxial with a main axis of the subassembly, and each includes an annular radial wall, the annular radial walls facing each other while bearing axially against each other, and
wherein the second component includes a plurality of clamping tabs, which clamping tabs cooperate with the first component to impart an axial force pressing the annular radial walls against one another.
