PURPOSE: A safety device of a wedge type hydraulic coupling is provided to prevent safety accidents by fixing a coupling body and a piston nut to predetermined positions when the pressure of a cylinder is removed due to various factors during driving. CONSTITUTION: A safety device of a wedge type hydraulic coupling comprises a stopper (8). The stopper fixes a coupling body (1) and a piston nut (4) to predetermined positions of a tapered pipe. The stopper comprises a fixed bracket (82), a coupling bolt (84), and a fixing nut (85). The fixed bracket is fixed to the piston nut with a fixing bolt (81). The coupling bolt is inserted into a coupling hole of the fixed bracket and is coupled to the coupling body. The fixing nut is coupled to the coupling hole of the fixed bracket and is connected to the coupling bolt in order to fix the coupling bolt to the fixed bracket.
