The invention discloses a limiting sleeve cover assembly for installing a joint. The limiting sleeve cover assembly comprises a limiting piece clip and a sleeve cover bolt, wherein an open clamping groove is formed in one end of the limiting piece clip, an assembly part which is matched with the open clamping groove is arranged on one end of the sleeve cover bolt, and the sleeve cover bolt passes through the assembly part and is inserted into the open clamping groove so as to be fixedly connected; furthermore, the assembly part is stepped; furthermore, two elastic insertion holes are formed in the sleeve cover bolt; and furthermore, buckles which are matched with the elastic insertion holes are arranged on the limiting piece clip. The limiting sleeve cover assembly has the beneficial effects that the structure of an original limiting sleeve cover is changed, so that the limiting sleeve cover is divided into two parts including the sleeve cover bolt and the limiting piece clip, the installation steps of cold riveting of the sleeve cover bolt, pressure casting of a steel cable joint on the end and final installation of the limiting piece clip are realized, and the problem of difficulty in installation is solved.
