ABSTRACT:
There is provided a collapsible barrel-shaped barricade which telescopes within itself for compact storage. Particularly, a solid and heavy base is provided for stability and a series of telescoping ring members are mounted thereon; the lowest ring being mounted to the base and upper rings being concentric with the lower ring. The concentric rings are arranged to interlock by placement of a tab from an inner ring into a horizontal slot on the inside of an outer ring. This interlock operates to hold the rings in an extended position when the barricade is in use.
