Abstract
A locking and fixing device for a heat shield element, which heat shield element can be arranged along a heat shield row axially directly next to at least one blade provided in a blade row and has, axially facing the blade, at least two projections of rib-like design which are spaced apart in the circular circumferential direction, are raised above a side wall section facing the blade and define a clear intermediate space which extends in the circular circumferential direction and into which a locking lug provided on the blade can be fitted. Further disclosed is at least one rib-like projection, on its side facing away from the clear intermediate space, providing an extension which extends in the circular circumferential direction, is connected to the projection and the side wall section and rises above the side wall section at most up to the rib height of the projection.
