Abstract
A locking device for locking an expandable support device, where the locking device includes a spring device integral with the expandable support device, and the spring device includes an end portion, a first flexible arm, and a second flexible arm. A first aperture of the spring device is adapted to position the fastener associated with the first rotational position and a second aperture of the spring device is adapted to position the fastener associated with the second rotational position. The first flexible arm and second flexible arm are adapted to flex outward and allow passage of the fastener head when an inward pressure is applied to the fastener positioned in the second aperture. The first flexible arm and the second flexible arms are adapted to collapse to their unflexed position after the fastener head has completed passage through the spring device, such that the first flexible arm and the second flexible arm are adapted to cover the fastener head and prevent the fastener from backing out.
