This invention is concerned with a locking device for a drum which seals and locks the bung hole and vent hole of 35 or 55 gallon drums to prevent unauthorized access thereto. The device includes two swivel locks, each consisting of a lock cap containing an externally threaded base and a swivel and a lock bar. After the swivel locks are threaded into the bung hole and vent hole, the swivels are rotated until their holes align. A lock bar having a flanged end of greater width than the hole of the swivel and a hole at its other end is passed through the holes. The shackle of a padlock or other locking device is then passed through the lock bar hole and locked. Means for rotatably retaining the swivel in the lock cap are also provided.
