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. When the cover is placed over the valve and is secured, it has the added benefit of providing protection of the valve during transport of the tank.

[ What is claimed is:] [1.] A cover for a fluid containing vessel having a fluid control valve with a fluid transfer line connection, said cover being an integral component comprising:(a) resilient, flexibly biased expandable housing means for placement in position over the valve for preventing access to the valve, said housing means having an open bottom and a top configured such that the housing means forms an enclosure;(b) separation means in the housing means which is normally biased closed as a result of the biased nature of the housing means, said separation means configured to be biased open to enhance the expandability of the housing, whereby when the separation means is biased open, the housing means expands to permit the line connection to pass through the separation means; and(c) resilient, flexibly biased locking means for opening the separation means and for securing the cover to the vessel, said locking means preventing access to the valve when the housing means is placed in position over the valve and the separation means is biased closed.
