Abstract

A cargo strap buckle comprises two sets of pins arranged between opposing plates. One set of pins is fixed to the plates and positioned between the other set of pins. The pins of the other set are separable or capable of disengagement from the plates or buckle to facilitate looping a cargo strap around the pins. In one mode, one pin can be totally disengaged with one pin only being partially disengaged. In another mode, both pins can be partially disengaged and one or both pins can also be longitudinally adjustable with respect to the plates. In one use, the cargo strap is first fed between the fixed pins and the pins are separated from the plates to facilitates strap attachment. In another use, when one or both pins are not totally removable from the buckle, the pin or pins is moved with respect to the plates for strap attachment. In either mode, the strap can then be tensioned for securing cargo or the like. The separable pins minimize strap waste by eliminating strap cutting for strap attachment or removal.
