Abstract: A tension blind including a covering structure, a movable rail, two lifting cords, and two fixing units is disclosed. Each of the lifting cords is connected to a first fixture with an end, passes through the covering structure and the movable rail, and is connected to a fixing unit installed on a second fixture with the other end. The fixing unit includes a connected member fixed to the second fixture, and a connecting member which is connected to an end of the lifting cord and to the connected member detachably. If the lifting cord is forced by a non-vertical pull greater than a preset combined value between the connecting member and the connected member, the connecting member is automatically disconnected from the connected member in order to release the lifting cord.
