The gas turbine has a number of turbine blades (12), each fitted to a turbine shaft via a blade foot (20) and having an internal cooling medium channel (24) coupled to cooling medium feed and return channels (26,34) integrated in the turbine shaft. The connection ends of the feed and return channels each have a widened cross-section and a matching cross-section sealing sleeve (30,36) which can slide in the longitudinal direction.
