ABSTRACT:
The invention relates to a signaling column with levels which are assembled by a relative pivoting limited in amplitude and interconnected by axially-extending conductors. The body of a level includes a locking bar which extends axially to penetrate an opening in an adjacent level and abuts an edge of the opening on a rotation attempt. The ends of the bar may be displaced and the opening is of such a size as to accommodate the top end of a relevant bar and the bottom end of the bar above.
