To construct single pipes to connect a plurality of barricade legs with single piping clamps and to provide the barricade legs for lighting lights in proper positions of this barricade.

In barricade legs, barricade leg bodies 1 are molded of plastic, upper reinforced bars 2 and lower reinforced bars 3 are constructed in approximately intermediate sections of the leg bodies 1 vertically and near to the lower parts of the legs, and a plurality of barricade leg bodies 1 are arranged in the intermediate sections between the upper reinforced bars 2 and lower reinforced bars 3 to provide single piping clamps 4 and 5 connected with single pipes. Then, when the barricade leg bodies 1 are molded of a plastic, plastic holding bodies 6 are monolithically formed of the top sections of the barricade leg bodies 1 in the vertical directions on the top sections, and light bodies (a) equipped with lights 7 in the holding bodies 6' and cell storage sections 7' lighting the lights 7 are inserted in the holding bodies 6 from upper opening sections 6' of the holding bodies 6 to fix.
