The present invention relates to a door with an anti-fall safety system. According to the invention, the anti-fall system comprises two elementary devices located on each side of the apron. Each device itself comprises a flat cam 21 provided, opposite its joint, with a convex rim 21b having a toothing 21c, and a tab 24 forming a hook 24a. This makes it possible, if the cable 9 breaks, to grip the bottom of the adjacent guide rail between the toothing 21c and the hook 24a. <IMAGE>
