Abstract: A partition apparatus or system having one or more panels each releasably fixed with respect to a hinge element. The hinge element has at least one hinge leaf, each with an outer edge. Each hinge leaf has at least one opening, preferably multiple openings, extending from the outer edge in a direction inward toward the hinge pin. The panel at least partially defines a slot. A male connector is mounted within the slot. The hinge leaf can be inserted within the slot so that the male connector engages within the opening of the hinge leaf. The opening of the hinge leaf can be shaped so that the hinge element is releasably fixed with respect to the panel.
