Abstract: An adjustable cargo tie-down includes a cam buckle and a hook that couple together in a retained manner to reduce accidental disengagement. The cam buckle includes a frame that supports a rear pin and a spring-biased locking cam that clamps a webbing strap. The cam buckle also includes a pin for the hook and a retention feature adjacent the engagement bar, such as a wall or rib extending from a floor of the buckle. The hook receives the pin and is rotatable between a retained orientation, in which the retention feature blocks sliding release, and a release orientation that permits separation. In some examples, the hook includes a spring-loaded locking pin that further prevents unintended release.
