A venetian blind includes a top rail and a bottom rail linked by two ladder ropes. The ladder rope has a first vertical portion, a second vertical portion, transverse portions connected between the first and second vertical portions, and loop portions connected to the first vertical portion. The slat is supported by the transverse portion and has two holes, two openings, and two slots communicating between the holes and the openings. The loop portions penetrate into the holes from the openings through the slots so as to be mounted around one long edges of the slats. The peripheral wall of the hole has a guiding surface and a positioning portion. When the slats are tilted from a horizontal position to a tilted position, the loop portions are moved along the guiding surfaces to the positioning portions. As such, the present invention is structurally simple and easy to be assembled.
