ABSTRACT:
A locking device for selectively preventing access to the valve handles of a domestic water tap. The locking device is adapted to prevent a child from playing with the hot water tap handle and potentially getting burned by the hot water emanating from the hot water tap. The locking device has a pair of handle enclosing components which are adapted to enclose the tap handles and prevent access to the latter. Each handle enclosing component has a substantially concave-shaped wall defining a substantially hollow body. Each substantially concave-shaped wall has a corresponding peripheral edge defining a lateral aperture. The handle enclosing components are linked together by a pair of connecting rods extending from the respective peripheral edges of the handle enclosing component. Both connecting rods are attached to a locking block positioned intermediate the handle enclosing components. The locking block slidably receives the connecting rods and allows the handle enclosing components to be locked in a predetermined spaced relationship relatively to one another. The user is thus adapted to initially position the handle enclosing components on each side of the tap handles and then to slide the handle enclosing components over the tap handles. Once the tap handles are enclosed inside the handle enclosing components, the user prevents the handle enclosing components from being laterally withdrawn from the tap handles by using the locking block.
