1. A hydrant locking device adapted for interconnection to a hydrant body having an inlet that is associated with a fluid pipe, an outlet, and a fluid control portion that includes a threaded portion that surrounds a stem screw and receives a packing nut, comprising: a lock body having a threaded end adapted to interconnect to the threaded portion of the hydrant body, a cavity and an aperture associating said cavity to an outer surface of said lock body;a lock having a selectively movable bolt and an outer surface with a groove integrated therein, said lock being fixed within said cavity of said lock body in a predetermined orientation;a cover comprised of a cylindrical outer surface and a cylindrical inner surface positioned over said outer surface of said lock body wherein said lock body and said lock are concealed with only an outer surface of said lock exposed, said cover also including a portion that extends into an internal volume of said cover that has a plurality of fingers that engage said groove to operably fix said cover to said lock, said cover being freely rotatable about said lock body wherein said lock remains stationary relative to said lock body; anda key that is associated with said lock to selectively move said movable bolt, wherein when said movable bolt is in a first, extended position of use, said lock and said associated cover are interconnected to said lock body, and in a second, retracted position of use, said lock and said associated cover are not interconnected to said lock body wherein said lock and associated cover can be removed from said lock body. 2. The device of claim 1, wherein said plurality of fingers are resiliently deflectable and terminate in a tip that interface with said groove of said lock. 3. The device of claim 1, wherein said lock is a tubular pin tumbler lock. 4. The device of claim 1, wherein said lock restricts access to the stem screw. 5. In combination a fluid hydrant and a locking device therefore, comprising: a hydrant comprising:a pipe with a first end and a second end, said pipe having a longitudinal axis,a housing associated with said first end of said pipe,an inlet valve associated with said second end of said pipe,a rod with a first end and a second end positioned within said pipe,a plunger associated said second end of said rod that cooperates with said inlet valve to selectively open and close said inlet valve, wherein rotation of said rod transitions said rod between a first position that closes said inlet valve and a second position that opens said inlet valve,a stem screw, anda drain valve with a first end operably associated with said stem screw and a second end operatively associated with said first end of said rod, wherein rotation of said stem screw moves said drain valve along said longitudinal axis, said drain valve being associated with said rod whereby said rod is moved between said first position and said second position, wherein said drain valve is substantially prevented from rotating, and wherein said stem screw does not move substantially along said longitudinal axis; anda lock, comprising:a lock body having a threaded end interconnected to the threaded portion of said hydrant housing, a cavity and an aperture associating said cavity to an outer surface of said lock body;a lock having a selectively movable bolt and an outer surface with a groove integrated therein, said lock being fixed within said cavity of said lock body in a predetermined orientation;a cover comprised of a cylindrical outer surface and a cylindrical inner surface positioned over said outer surface of said lock body wherein said lock body and said lock are concealed with only an outer surface of said lock exposed, said cover also including a portion that extends into an internal volume of said cover that has a plurality of fingers that engage said groove to operably fix said cover to said lock, said cover being freely rotatable about said lock body wherein said lock remains stationary relative to said lock body; anda key that is associated with said lock to selectively move said movable bolt, wherein when said movable bolt is in a first, extended position of use, said lock and said associated cover are interconnected to said lock body, and in a second, retracted position of use, said lock and said associated cover are not interconnected to said lock body wherein said lock and associated cover can be removed from said lock body. 6. The combination of claim 5, wherein said plurality of fingers are resiliently deflectable and terminate in a tip that interface with said groove of said lock. 7. The combination of claim 5, wherein said lock is a tubular pin tumbler lock. 8. The combination of claim 5, wherein said lock restricts access to the stem screw.
