Abstract
A safety release pin for locking the operating mechanism of a fire extinguisher includes a shank having a blunt nose portion at one end thereof and having a portion of reduced diameter rearward of the nose portion defining parallel flat surfaces, and a pair of elongated locking members are pivotally mounted to the shank, each overlying a different one of the flat surfaces, and each defining a cam surface which coacts with surfaces of the operating mechanisms as the pin is inserted to pivot the locking members towards the flat surfaces to facilitate insertion, rearward movement being limited by projections on the undersurface of the locking members, maintaining interference betwen the locking members and the apparatus. When the pin is withdrawn, detent surfaces of the locking members coact with surfaces of the operating mechanism to rotate the locking members forwardly, severing the locking members from the shank.
