Abstract
A locking device for use with a gas flow distribution device to be connected to a source of gas under pressure. The device has a yoke for securement to the source and a fastening screw threaded in the yoke for securing the device to the gas source. The locking screw has a tee-shaped handle. The locking device has a collar including a sleeve defining opposed openings for engagement of the yoke to permit longitudinal movement relative to the yoke but substantially prevents rotation of the sleeve relative to the yoke. The collar has a yoke-remote portion including a plurality of handle-engaging recesses. A spring biases the collar outwardly from the yoke into locking engagement with the handle for preventing unintended unfastening of the screw.
