A technique is described whereby a clamp-locking device provides a simple low cost method of locking and unlocking a shaft mechanism, such as where frequent adjustments are required on adjoining shaft assemblies. The clamp-locking device is unique in that only two parts are required, clamping lever 10 and split collet 11, as shown in Figs. 1 and 2. Clamping lever 10 has pin 12, which could be molded as part of lever 10, positioned between cams 13 so that clamping lever 10 can be snapped into detent 14 or split collet 11. Lever 10 is designed to provide a camming action, so that when the lever is rotated as shown in Fig. 2, it will cause split collet 11, which is positioned onto external shaft 15, to provide clamping action on the shaft.
