A cam type buckle pinches a strap between a transverse blade of a pivotable tongue of the buckle and a laterally and transversely extending surface of a base of the buckle to pinch the strap in the longitudinal direction (the direction the strap extends through the buckle from end-to-end) and so that the frictional force exerted by the strap on the blade where the strap is pinched by the blade against the surface tends to rotate the tongue into a closed position.
