Apparatus for clamping a workpiece, such as the end portion of a conveyor belt, includes a link member having an upper end portion and a lower end portion with a receiving member secured intermediate the end portions for horizontally supporting the workpiece. A bent lever having a first end portion angularly disposed relative to a second end portion is pivotally connected at a fulcrum point to the link member upper end portion. An arcuate blade member having a clamping surface is secured to and projects outwardly from the lever arm first end portion above the receiving member. An actuator is pivotally connected at one end portion to the lever second end portion and at the opposite end to the lower end portion of the link member. The application of a selected force to the actuator in a direction away from the link member pivots the lever about the fulcrum point on the link member downwardly and urges the blade clamping surface into frictional engagement with the workpiece. The actuating force applied to the actuator is multiplied by the lever to exert upon the workpiece a resultant clamping force of substantially greater magnitude to rigidly secure the workpiece between the blade member and receiving member.
