摘要

Fixing device for a blade mounting of a compressor or turbine stage of a gas turbine system comprises a wedge element (43) having at least one connecting element (45) for the side of a blade (31, 32). At least one of the two blades adjacent to the wedge element has a counter-contour (46) corresponding to the connecting element so that the wedge element and the blade engage with each other with a form-locking connection. Preferred Features: The connecting element and the corresponding counter-contour are designed as a dovetail joint.
