A device for preventing a belt from being pulled from a retractor comprises a clamp holder and a base member having closely spaced surfaces defining a gap through which the belt passes and from which the belt runs off forwardly at an angle away from the base member. The holder receives a clamp which has a gripping surface protruding slightly from the holder surface and, in part, defining the gap. The holder is pivoted on the base member, and the clamp and holder are spring-loaded about the pivot axis in a direction which holds the clamp out of engagement with the belt. An abrupt force tending to pull the belt abruptly forward through the gap forces the holder to pivot or rock rearwardly, thus engaging the gripping surface of the clamp with the belt. Forwardly oblique, transverse wedging surfaces on the clamp and clamp holder wedge the clamp tightly against the belt and prevent it from being pulled forward.
