Abstract
A quick change tool holder including two basic component assemblies, the first component assembly having a central boss portion and the second component assembly having a recess to receive the boss portion when the two component assemblies are attached together. A channel formed in the boss portion is engaged by a pivotally mounted lock bar member when the component assemblies are attached together. The lock bar is moved out of the channel which permits separation of one component assembly from the other by the action of air pressure against a piston.
