ABSTRACT:
The novel collapsible signalling post is provided with a weakened section characterized by an helical groove carved on the periphery of a tubular member to mounted between an anchoring member and a rod member supporting a sign. The groove provides a weakened section adapted to split open along a portion thereof and upon bending caused by a lateral force exerted on the signalling post, the two end portions of the tubular member remain connected to each other by the unfolded spires formed between the helicoidal thread.
