Locally you can try a well-stocked automotive store or Lowe's. At Lowe's you have to look into the parts drawers they have under the bagged fasteners. You may not find exactly the same dimensions as these, but perhaps there will be something close.
If you need these in high quantity, two leaders in plastics fasteners are Volt Plastics and Micro-Plastics. More than likely, one of these, or else Keystone, is where outfits like Mouser and Digikey get their stock. It's usually (much) cheaper direct.

Sorry but I don't see any examples of what I pictured. I looked in the fasteners section.
