A clamping device including a generally C-shaped frame having first and second ends. The first end of the C-shaped frame is uniquely provided with a first through bore and a second angularly extending bore. The device further includes an elongated threaded rod having an external thread and being telescopically movable within the through bore. A novel control member having a rack-like upper surface is disposed within the second bore of the C-clamp frame for movement into and out of the engagement with the threaded rod in response to manual force exerted on the control member and also in response to forces exerted on the out-board end of the threaded rod urging it in a direction toward engagement with the work piece.
