Abstract: A valve guard for a water faucet with a manually operated control valve. The guard has two substantially identical sections that when joined together in a closed position form a generally spherical surface with a lower cut off opening portion. A spring hinge joins the sections together at facing side edges to normally maintain the sections together in a closed position. A child has insufficient hand strength to pry the two joined sections apart while an adult may easy separate them. The guard is placed over the valve to be controlled with the opened lower portion first. Due to the exposed spherical shape of the closed guard enclosure and the flat bottom opening edge, the guard is difficult for small hands to grasp and when touched may freely rotate about the enclosed valve. The guard is sized relative to the valve structure to be protected. Thus, it may be fitted over the hot water control valve of a two control valve faucet or over the one control valve of a single control valve lever.

Abstract: An integral, one piece cover for a cylinder tank vessel valve is provided with a flexibly expandable housing, preferably formed of resilient molded plastic. The housing has a slot at the bottom, along one side. There is an opening formed adjacent to the slot. Dual locking tabs on the housing are adapted to receive a locking device. The cover is placed over the valve of a tank or any other upwardly extending valve by spreading the tabs apart, thus causing the slot to open and expand the lower portion of the housing. In this expanded state, the slot passes over the valve's hose or piping connection. The connection is then positioned within the opening and the tabs are released. The resilient nature of the housing biases the slots to close around the connector. The housing can At then be secured with a lock through the locking tabs. Once secured, the valve cannot be accessed without removal of the lock.
