Pivotable safety barrier in the manner of a lock for platforms, with an inner and outer gate, each of which is formed from a large number of elements (1c, 2c, 3c; 1d, 2d, 3d) which are arranged above one another and which are movable independently of one another, the lower elements (1c, 1d) of the two gates being interconnected in such a manner that the movement of the lower element (1d) of one gate in the vertical direction leads to the movement of the lower element (1c) of the other gate in the opposite vertical direction and that the lower element (1d) of the first gate subsequently consecutively draws the elements (2d, 3d) of the same gate, which are arranged above one another, in the first-mentioned vertical direction, while the other elements (2c, 3c) of the other gate are drawn along consecutively in the second vertical direction. <IMAGE>
