A guard defines an inner seat comprising an open channel shaped to receive a shackle and extend partially around the shackle. The guard further includes an outer seat positioned opposite the open channel and shaped to support a strap passing through the shackle. A tether is fastened to the guard and defines a fastener for securing to a closure pin passing through the shackle. The fastener may be a hole formed in the tether and a barb formed on the tether offset from the hole, a barb on the tether that inserts through a hole in the closure pin, a cup on the tether that is positioned over an end of the closure pin, or a hooked or straight tether. The tether and fastener may be secured to a spacer through which the closure pin is inserted. A closure pin may insert through a pair of spacers.
