Abstract
A locking device to keep two spaced apart positionable heads in place. The disclosed locking device can keep two hex shaped adjustable relief valve heads (34,44) in place. The locking device (10) is punched out of a flat thin sheet metal plate. An elongated opening (12) punched out in the plate has a length (14) which is greater than the furthest separation of the two adjustable heads (34,44). The in flat width (16) of the elongated opening (12) in the sheet metal plate is large enough to fit over the adjustable heads. During use, the plate is bent to decrease the effective width of the opening (12) so that it is smaller than the associated adjustable heads. The locking device (10) is then forced over the two heads (34,44) to engage a flat portion thereof and prevent relative movement.
