A drawer for filing cards which includes a retaining rod for holding file cards and a release knob which is normally recessed in the front panel of the drawer to block tampering. The rod and knob are normally held in position by a pair of metal wings secured to the rod which block withdrawal through a hole in the panel. A release plate can be pressed toward the panel to compress the wings and push the knob to a position where it may be grasped and withdrawn.
