A buckle for use with a belt or with strapping in which the bucket uses magnetic attraction forces to apply a clamping force on the belt or strap, when the buckle assembly components are in a first predetermined orientation. Typically, a plurality of magnets is used, and when the buckle assembly is rotated to a second predetermined position, the magnets are moved from a state where they attract one another, to a position where they repel one another. In this second predetermined orientation, the buckle components are forced apart by the repulsive forces so as to create a larger gap between the buckle components, and thus allow the belt or strap material to move freely within the gap. The buckle is preferably held in the second predetermined orientation by a restraint device such as a pin located within a recess on the corresponding rotating assembly. However, a slight depression and rotation of the buckle moves the buckle components out of the restraint device, and allows the magnets to effect rotation of the buckle assembly back to the first orientation position, and thus, decrease the size of the gap between the buckle components. This once again clamps the belt or strap material within the gap. A simple magnetic clamping device is provided.
