The element (1) has an erecting component (7), which is slidably supported between a head (3) and a nut (6) on a screw shaft. A number of spreading segments (9) is arranged between an erecting inclined plane (8) and the head, and another erecting inclined plane (8') and the nut approximately around the screw shaft. Ends of the spreading segments, which turn toward the erecting components, are moved away or spreaded during approaching of the head to the nut through run onto ground on the erecting inclined plane from the screw shaft. An independent claim is also included for a tubular radiator with a recess. |
