One of the buckles on one of my motorcycle covers decided that it had too much of this world recently.
Not ideal. Luckily new buckles are pretty cheap and are, additionally, a bit nicer than these bargain basement ones.
It took a bit of doing to replace the one side though. The male portion just threaded on an open-ended strap like you'd normally see, but the female side was sewn into a loop that I had to disassemble and then stitch back together.
Wasn't too bad though, maybe took a half hour of actual work, including hauling out the sewing machine and setting it up.
