Abstract: The invention is a new type of locking mechanism for office panel systems which allows quick joining or separation of connecting panels without the need for tools. This is accomplished by the invention of a spring-loaded "tab and slot" locking mechanism, whereby the opposing tabs from the connecting vertical panel end, enter and lock into matching slots on the other panels by way of a spring-loaded sliding locking bar. Joining adjacent panels requires only that the panels be aligned and firmly pushed together, while separation is allowed by pulling down on the metal rings attached to the bottom of the opposing locking bars and pulling the panels apart.
