ABSTRACT:
A locking device for clamping plates, such as printing plates, in place includes a housing. A jaw is in the housing with a plurality of sets of clamp members mounted in the jaw. Each of the clamp members has rounded clamp surfaces. Spacers separate the sets of clamp members from each other. A fixed stop member is located at one end of the jaw and an actuating member is movably mounted at the other end of the jaw. When the actuating member is manipulated to move further into the jaw the spacers press against the clamp members to displace a clamp member of each set into its clamping or locking position with the plate clamped between the inside jaw and a wall of the housing.
