Abstract: An apparatus for attaching a wheeled element, such as a caster, comprises a caster bracket with means for engaging the caster plate of a caster. The caster is affixed to the caster plate and is then engaged with the caster bracket. The caster bracket is preferably flanged for slidably receiving the caster plate which is positively held in place with the aid of a flexible locking member affixed to the caster bracket. The flexible member is operatively arranged to substantially immobilize the caster plate when the member engages a surface of a slot in the caster plate. The flexible locking member further comprises a tab extension operatively arranged to allow disengagement of the caster safely by direct hand/finger engagement without requiring tools.
