A socket designed for manually siding onto a valve adapted for use in a pipe line and enabling rotational movement of the valve and thereby connection to and disconnection from the pipe line. The socket has a square drive bore at a longitudinal end thereof to enable a square drive of a wrench to be inserted therein for rotation thereof. The recess of the socket is open box shaped and dimensioned to fit snugly around the outer surfaces of the valve for snug engagement of the valve to provide rotation of the valve via rotation of the socket. The socket also has semicircular openings at opposing lateral portions thereof to receive control and mounting structures of a ball valve structure therein and fit snugly therearound to provide more positive engagement of the valve. The inner walls of the socket are flat to fit snugly against corresponding flat surfaces of the valve to provide more positive engagement of the valve. In addition, the socket is provided with a post at an inner surface end portion thereof which fits within a pipe fitting at an end of the valve to provide a firm and stable fit of the socket on the valve.
