KEEJEA12 Pack 3/4 inch Plastic Ladder Slider Adjust Lock Buckles for Backpack Straps 20mm Webbing

I used these clips to replace the strap clips on new Crocs. My dog chewed the original clips up. Croc clips are not available anywhere - they must be made from unobtainium. Croc customer service was terrible and of no help. These plastic clips were the only ones that were even remotely similar. I drilled a hole in the tab and pinned the clip to the shoe. Not what the clips were intended for, but it worked. Clips seem strong and durable.

These buckles are real neat

Made a hiking backpack, used on shoulder straps. Intentionally loaded it heavy, about 50 pounds and they both immediately snapped. Probably ok for lighter applications. Glad it didn't happen at a trailhead.

It's fine for my use, but it's not as burly as typical outdoor buckles.
