Abstract
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.
