A buckle has a strap attaching structure which has at least one shock absorbing flexible portion attached to the strap attaching structure. The shock absorbing flexible portion can be a flexible fin, which extends longitudinally along the strap attaching structure. The free end of the fin extends away from the strap attaching structure. The strap is wrapped around the strap attaching structure and the flexible portion. When a force is exerted against the strap attaching structure by pulling on the strap, the strap presses against the flexible portion and causes it to bend, thus decelerating the load caused by the strap and absorbing the initial force on the buckle.
