A removable block set for a window covering includes an inner block, an outer block and at least a connecting block between the inner block and the outer block. The inner block, the connecting block and the outer block are assembled together through the tenons and the slot tunnels therebetween, and the removable block set can be installed at two sections of the cases of the upper and the lower rails of the window covering. Therefore, through changing the whole length of the removable block set, the length of the upper and the lower rails (including the removable block set) may have a better conformation to the width of the window, and a more convenient installation of the window covering can be provided.
