Just noticed couple days ago that the clip was missing off my rear caliper. How could this have happened considering I've never touched the brakes. What purpose do those clips/retainers serve and is it safe to drive until I get another one?

I've been driving now for a while without that clip on/off the highway with only one issue which I don't know if its related. When I go in "reverse" (and only in reverse) and then stop on the brake (don't have to stomp on it heavily) i hear a clunk which seems to be coming from the rear of the car. When I then go forward, I don't get the same noise...

Anyone know if this missing caliper clip/retainer is to blame?
