A locking device is described for oil field valves or the like including: a lock base member having a recessed portion extending from a bottom surface of the base member. The recessed portion is configured to fit over a valve flange and to a body of a valve. An opening in the base member extends through the base member so that when the base member is located on a valve body, a valve stem of a valve can project through the base member and be manipulated with the base member in position on a valve body. At least two first locking bores extend downwardly from an upper surface of the base member. At least two second locking bores extend inwardly from the respective sides of the base member and partially intersect the locking bores.
