An air supply bushing arrangement is disclosed for radial bridging of a double-walled flame tube structure. The bushings are designed to be inserted in a readily interchangeable fashion in the respective openings of an outer and inner flame tube section, each bushing having an annular spring element which is compressed upon insertion and which, after the bushing has reached the operating position, snaps into a circumferential groove disposed at the edge of the opening of one of the two flame tube sections.
