A telescopic roadblock comprises a base and a cone on the base. The cone is of telescopic structure defined by a plurality of inter-linked concentric hard conical sleeves having the same height and decreasing diameters with two adjacent hard conical sleeves being connected together by a soft material, whereby the cone can be easily compressed up to the same height as a hard conical sleeve. The hard conical sleeve with the smallest diameter is set on the topmost end. The outer surface of the cone is coated with reflectorizing material. The roadblock is small, convenient, eye-catching and easy to carry.

1. A telescopic roadblock comprising a base, an upper end, and a plurality of conical sleeves formed of a first material and spaced from each other along the length of the roadblock between said base and said upper end, each said conical sleeve comprising an upper terminal end, a lower terminal end and an outer diameter that increase from said upper terminal end to said lower terminal end, and a second material extending between adjacent conical sleeves along the length of the roadblock, wherein said second material is softer than said first material.
