The height-adjustable street-cap has an upper part (1) serving for incorporation of a cover and a lower part (2) supporting the upper part. The upper part with a cylindrical pipe section (3) is inserted into the lower part for height adjustment and is telescopically movable. The clamping units (6) that are projecting inwards are assigned to the upper edge of the lower part. The clamping units generate a lower clamping effect between the upper part and the lower part. The clamping units are designed as slotted or segmented circular ring projecting inwards. |
