ABSTRACT:
A lockable valve having features which impede unauthorized removal of the valve from a conduit to which the valve is connected. The housing of the valve has a passageway. A valve element is movably mounted to the housing for occluding the passageway. A structure operatively associated with the valve element impedes disengagement of the valve from the conduit when the valve element is in a first position. Preferably, the housing of the valve is attachable to the conduit by a fitting which is movably mounted to the housing and such fitting is accessible only through the passageway of the housing when the valve is mounted to a conduit. When the valve element occludes the passageway, it blocks access to the fitting and hence serves as part of the disengagement-impeding structure. The valve may include lugs for connecting the fitting to the housing for movement therewith when valve element is in a second position. If such lugs are provided, the valve can be disengaged from the conduit by moving the valve element to the second position and then moving the housing.
