Abstract

The ratchet buckle for tightening a strap under a ratchet action provides a retention arm that constrains folded excess strap to the buckle to prevent it from flapping free during transport of cargo that the strap secures. A guard is provided outside a crank arm that is rotatably journaled to a base by a spindle on its forward end. The crank arm is secured to the guard intermediate the length of the guard with the guard extending rearward of the crank arm. The guard thus covers a ratchet wheel and the crank arm and with the crank arm forms an effective double-layered crank arm. The retention arm is rotatable on a handle shaft mounted to the guard rearward end, biased down onto folded excess strap.
