ABSTRACT:
A cam lock device for flexible ropes, cords or similar elongated materials has a pivotable cam element with a convexly curved, preferably knurled periphery and an eccentrically located pivot point supporting it on a base. A stationary cam surface integral with the base faces the cam element and includes at least one curved surface projecting towards the cam element for wedging the elongated material between the cam element and the stationary cam surface. A retaining edge above the stationary cam surface is spaced from the base a sufficient distance to allow pivoting of the cam element in a channel between the base and the edge. A pivot pin through the pivot point is supported on opposite ends thus stably supporting the cam element.
