The invention refers to improvements in variable correcting and/or tuning capacitors. The improved capacitor consists of a cylindrical body 1 made of tetrafluoroethylene into which a bolt 5 is screwed that expands the material of the cylindrical body outwards, to be housed in radial orifices 4, offset 90 degree from one another, provided for this purpose in the corresponding metal sleeve 3 mounted in this cylindrical body 1, this forming the actual dielectric insulator of the capacitor. The device in question is fastened into the frame 2 by means of a knurled metal ring 7, with appropriate dimensions so that, when the bolt 5 is screwed in, as it passes through it a displacement of material takes place from the latter to the interior, ensuring the electrical contact between the two elements. <IMAGE>
