Abstract: A support device for rapid attachment to a structural component of a bed, stretcher, gurney or the like, for supporting a device on behalf of a patient. This device comprises first and second clamping jaws operatively associated with an elongate rod, with each of the jaws having at least one active surface. A manually operable component is utilized for bringing about movement along the elongate rod of one of the jaws relative to the other jaw, with the manually operable component enabling the active surfaces of the first and second jaws to converge in a generally aligned manner. The active surfaces of the jaws are placable on either side of a structural component of a bed, stretcher, gurney or the like, with continued operation of the manually operable component causing the active jaw surfaces to bear closely against and thereafter tightly grasp the structural component and thus form a sturdy mounting for the elongate rod.
