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.
