Each flange is rigidly connected to the respective vertical post and has a peripheral portion surrounding the vertical post. This peripheral portion receives a hook of the pawl rigidly connected to the end of the respective horizontal bar and provided with a wedge to ensure engagement of the hook with the peripheral portion of the flange.
