PROBLEM TO BE SOLVED: To provide an implement for coupling barricades to each other which is made excellent in handleability, for example, by enabling performance as efficient as possible in operations of coupling/decoupling and storage/transport of A-shaped barricades wherein folding legs capable of being deployed in an approximate A shape are coupled to both ends of a bar made of a pipe, and by enabling the A-shaped barricades to be easily installed on the uneven ground and installed in such a manner as to surround a site indefinite in shape. SOLUTION: In the coupling implement A, a coupling bar 1 of a prescribed length, which is formed in an approximate gutter shape so as to be externally fitted into the bar 101 made of the pipe of the A-shaped barricade, serves as a main body, and a fixing means for engageably/disengageably fixing both ends of the coupling bar 1 to arbitrary places in the longitudinal direction of the bar 101 is assembled. Preferably, the fixing means comprises paired pinching members 3 and 3 which are formed with screw passing holes so as to pinch the outer peripheral surface of the bar 101 from both sides, fastening screws 4 and nuts 5 for the pinching members 3 and 3, and insertion cylinders 2 which are protrusively provided at both the ends of the coupling bar 1 so as to allow the insertion of the fastening screws 4 into them.
