Abstract: A vehicle door handle assembly comprises a handle pivotally connected to a base plate. The handle assembly is connected to a door sub-assembly by screws. The handle comprises a button which when depressed enables a restraint to be drawn into an operative position by a screw extending through the shut face of the door. When released, the button is locked in position by the restraint and prevents access to the screw. This screw, when removed permits the handle and plate to be pivoted away from one another to reveal another screw which may then be removed to remove the handle assembly from the door. The handle assembly can therefore be removed from the door from externally of the door but only when the door is open thus facilitating painting and maintenance.
