Abstract

The present invention relates to a heat shield (1) for shielding of hot areas, e.g. in a combustion engine, with at least one metal sheet layer (2), with the at least one metal sheet layer (2) comprising at least one passage opening (3) for taking-up a fastening means (5), and with at least one decoupling element (10) being arranged in at least one of the pas- sage openings (3) for at least partially decoupling or dampening the transfer of vibrations or heat from the at least one metal sheet layer (2) to the fastening means. Therein at least one of the at least one metal sheet layer (2) adjacent to the peripheral edge of the at least one passage opening (3) comprises at least one hole (6) and that the decoupling element (10) comprises at least one retainer element (14) being arranged on a first surface of the heat shield (1) radially outside the outer edge of the passage opening (3), which rests on one of the metal sheet layers (2) as well as at least one clamping element (16) arranged radially outside the outer edge of the passage opening (3), which at least one clamping element passes via the hole (6) through at least one of the metal sheet layers (2) and clamps behind at least one of these metal sheet layers (2).
