A stub-tuner for hyperfrequency coaxial line operating at high energy levels, comprising a first annular plate and a second annular plate arranged parallel to and one below the other, the plates being joined together by an outer ring and an inner ring which are respectively fixed to the outer and inner circumferences of the first and second annular plates, the rings being strips of blade-type contacts made of an elastic metallic material, means being provided for displacing the second annular plate relative to the first plate, these means comprising n push-jacks associated with a fluid-tight chamber into a fluid under pressure may be introduced, the n push-jacks so applying to the second plate a thrust directed perpendicularly thereof for pushing the second annular plate towards the first annular plate and so modifying the radius of curvature of the blade which rest under a predetermined pressure against the central and peripheral conductor walls, or push inner and outer strips of contactors, which are fixed upon the first plate, against the central and peripheral conductor walls.
