PROBLEM TO BE SOLVED: To provide a supporting leg for a barricade, which enables a reduction in weight by virtue of plastics molding and enables the easy and reliable fixation of a horizontal member without using a coupling member such as a clamp. SOLUTION: Paired plastic supports 1 and 1 are constituted by making ends of hinge beams 11 and 11, which are stretched for formation toward each other from the vicinity of a lower part, coupled together by a hinge. Upper parts of both the plastic supports 1 and 1 are provided with upper hook pieces 12 and 12 for holding an upper pole P1 by sandwiching it in between, and top surfaces of the hinge beams 11 and 11 are provided with under hook pieces 13 and 13 for holding an under pole P2 by sandwiching it in between. A technical means is adopted so that the hook pieces 13 and 13 can form an under grip part D in conjunction with the formation of an upper grip part U by the hook pieces 12 and 12 when the upper-side sections of both the supports 1 and 1 are made to abut on each other in the state of an approach to each other.
