I was taking 3 suitcases full of 70 lbs books each from New York to Nepal and wanted to make sure that the bags were secure and I that I could easily identify the bags.  These straps accomplished both. I was unsure of the plastic clips, but they held together well.  You can also tighten the straps up. In addition there are small idenity tags on the straps that you can fill out.  For not much money you get a great peace of mind!
