These practical clamping buckles are ideally suited to quickly and easily adjust the lengths of straps in sports bags, rucksacks, satchels etc. After determining the desired length, the strap can be fixed or released by the clamping device with one hand. The clamping buckles with strong closures are made of durable, break-proof plastic and are therefore ideally suited for outdoor use. They are available for various widths of strap - the width information relates to the internal dimensions of the clamping buckle and thus corresponds to the width of the straps to be used.
