A modular barrier comprising a pair of vertical posts, a pair of parallel rails and a holding assembly for retaining the ends of the rails inside the posts. Each of the posts has a facing vertical wall with the vertical wall having an upper window and a lower window. An upper tongue extends upwardly into the upper window while a dependent lower tongue extends into the lower window. Each of the rails has a first end disposed inside one of the posts and a second end disposed inside the other post. The posts have facing inside walls and each of the walls has an indentation adjacent the rails receiving a corresponding one of the tongues. The holding assembly is positioned entirely within a post and functions to push the rails towards each other so that the tongues are held in their corresponding indentations to maintain the posts and rails assembled.

A modular barrier comprising: a pair of spaced, vertical metallic tubular posts each having a facing vertical wall, each said vertical wall having an upper window and a lower window, each said vertical wall further including an upper tongue extending upwardly into said upper window and a dependent lower tongue extending into said lower window; an upper tubular metallic rail extending between said posts; a lower tubular metallic rail extending between said posts with said rails being parallel and having facing inside walls and outside walls, each said rail having a first end disposed inside one of said posts and a second end disposed inside the other of said posts, each of said facing inside walls having an indentation adjacent each said end receiving a corresponding one of the tongues, each of said windows being sized to receive its corresponding rail ends; and holding means pushing said rails towards each other and disposed inside each of said posts, each of said holding means engaging said outside walls of said rails and pushing each of said rails toward the other of said rails whereby said tongues are held in their corresponding indentations to maintain said posts and said rails assembled, and the rails are moved toward each other by the holding means so that said rails are firmly secured, said rail ends extending less than halfway through said posts, each of said holding means being disposed entirely within its corresponding post.
