A locking device for a chiropractic table is disclosed. The device includes a locking bar slidably received in a locking box. First and second locking plates are pivoted within the box and have locking apertures through which the locking bar extends. The plates are pivotally biased toward each other so that the plates are in a first position wherein locking edges of the aperture grip and lock the bar relative to the box. A rotatable plate is positioned between the plates to move the plates to a second position wherein the locking edges of the plates are out of contact with the locking bar to permit free movement of the locking bar relative to the box.
