In the case of a barrier for blocking off car parks, in particular in multistorey car parks, with a cantilevered, rigid barrier arm (2) articulated on a barrier post (1), and a supporting member (3) articulated between the barrier arm (2) and the barrier post (1), the articulation point (8) of the barrier arm (2) on the side of the barrier post being vertically movable, a particularly large space saving, in particular with regard to the maximum height in relation to the blocking-off width, combined with a simple structure and a stable closed position of the barrier arm (2), is achieved in that the vertically movable articulation point (8) of the barrier arm (2) occupies its highest position when the barrier is closed and its lowest position when the barrier is open, and an upper limit stop (15) for the vertically movable articulation point (8) is arranged on the barrier post (1). <IMAGE>
