A coupling for a fire hydrant-fire hose connection includes a first coupling member attached to the fire hydrant and a second coupling member attached to the fire hose wherein both the first and second coupling use a Storz connector. A butterfly valve is mounted within the first coupling to prevent access to the interior of the hydrant and a readily removable cover is placed over the first coupling member to shield the member when the hydrant is not in use.

In combination, a fire hydrant, a hose for connection to the fire hydrant, a connector having a fire coupling member mounted on the first hydrant and a second coupling member mounted on the hose, wherein the improvement comprises: means on the first coupling member for retrofitting the coupling member to the fire hydrant; a pair of identical projecting lugs and identical slot means on each of the coupling members, the slot means on one of the coupling members receiving the lugs of the other coupling member so as to couple the identical coupling members with a “sexless”connection; a butterfly valve within the first coupling member wherein said butterfly valve includes a pair of flaps biased closed by a spring means when there is no internal water pressure in the fire hydrant, thereby preventing access to the fire hydrant; and a cover member for fitting over the first coupling member while the hydrant is not in use, the cover member being a single piece and including a face portion for covering the opening through the first coupling, the cover member including a wall portion enclosing an internal area which approximates in configuration the area of the first coupling member, the cover member having lug means projecting therein, which lug means cooperates with the slot means of the first coupling member to lock the cover member of the first coupling member upon rotating the cover member with respect thereto, the cover member further including a linear slot in the face portion thereof, the slot having a closed bottom surface, the slot extending completely across the cover and opening radially thereof with widened portions at the ends thereof for forming finger grips in the face portion of the cover member.
