Not mad on these clip

I ordered four of these clips to hold some fabric on a dj stand. To be honest, I am not a fan of these and they don't seem very strong and feel like if i was to push them a little harder they would snap.

I don't like the fact that they do not open very wide, making you have to slip the fabric in which can be tricky. If the clip was to snap open fully and snap back, I feel this would've been a much better solution. I did not use them in the end and simply used some heavy duty tape instead.
