The invention relates to a covering element (2) for protecting components, especially components in a gas turbine (1), in a machine that is subjected to high thermal stress. The covering element (2) is provided with a wall (8) with a hot side (10) which can be exposed to a hot medium (M) and a cold side (12) which is opposite the hot side (10). The cold side (12) is provided with a cooling surface (14) that can be subjected to a coolant (K). Holding elements (28) are provided on the cold side (12). The invention also relates to an arrangement with a covering element (2) and with a support structure (34). The arrangement is tolerant with respect to thermal expansion.
