An apparatus for fixing hydraulic pipes for a zero tail swing excavator is provided, which can simplify an assembling process of hydraulic pipes and improve the workability by dividedly forming intermediate sides of the hydraulic pipes for supplying hydraulic fluid from a main control valve to hydraulic cylinders and jointly fixing the dividedly formed intermediate sides of the hydraulic pipes by a connection means in a narrow space between a boom and an upper swing structure due to the characteristic of the zero tail swing excavator. The apparatus for fixing hydraulic pipes includes a lower driving structure; an upper swing structure mounted on the lower driving structure to be swiveled; working devices fixed to the upper swing structure and having a boom, an arm, and a bucket driven by their hydraulic cylinders; boom fixing frames which are mounted on the upper swing structure and to which the boom is rotatably fixed; main pipes for supplying hydraulic fluid to the hydraulic cylinders, intermediate sides of the main pipes being dividedly formed and being jointly connected by a socket; and a bracket for fixing the main pipes, which is fixed to the boom fixing frames and to which the socket is fixed.
