    • A combustion chamber for a gas turbine engine includes a casing (2) and a heat shield (3), having ceramic tiles (4) arranged in rows and removably fastened to the casing (2) by respective supporting devices (5). The casing (2) has grooves (7) receiving the supporting devices (5) of a respective row of tiles (4). Each supporting device (5) has a first portion (10) in the form of a plate engaging a respective groove (7) and a second portion (12) in the form of a hooked head coupled to a coupling structure (8) of a respective tile (4). The first portions (10) of the supporting devices (5) of each tile (4) are separated from each other by a respective separation region at a central portion of the respective tile (4). First cooling holes (27) and second cooling holes (23) direct first cooling jets (28) and second cooling jets (25) against the first portions (10) and the second portions (12) of respective supporting device (5). Each supporting device (5) has a through opening at a connection of the first portion (10) and the second portion (12) and spacers (15) on a face (12c) of the respective second portion (12) and wherein a channel (16) aligned with the through opening (17) is defined between the face (12c), the spacers (15) and the tile (4).
