Abstract
A locking device comprises a stopper support fixed to the body of a fluid controller, and a stopper nonrotatably mounted on the stopper support and engageable with a channel opening-closing handle for preventing the rotation of the handle. The stopper mounted on the support is movable upward and downward between a locking position wherein the stopper engages with the handle and an unlocking position wherein the stopper is out of engagement with the handle. The stopper support is formed with an opening for fitting the controller body therein and an aperture for fitting the stopper therein. The stopper has a vertical portion slidably fitted in the aperture and formed with a lock attaching bore.
