The invention is an uncomplicated mechanism for preventing injury to a person's (especially a child's) hand when a fast-closing door slams against a door frame or jamb. The mechanism comprises a casing which is positioned within a hollowed out portion of the door. The casing is constructed with an opening disposed along the edge of the door panel. A metallic pendulum is housed and suspended within the casing such that the action of centrifugal force imparted by a fast-closing door will cause the pendulum to swing outwardly through the opening. A raised metal body is attached to the side molding of the door jamb and functions to engage the outwardly swung pendulum to prevent the door from completely closing.
