Ducky, mine are in the same condition. They are hard frozen. It's not a big deal and I don't try to force the clips. So only one side of my tub is actually clipped right now. I will go out today when I check my water and clip the other when the sun softens that other strap. I guess you could try to defrost them (maybe a hair dryer) and I probably would have worried about it too when I was new to tubbing. But just over night, I don't worry if my cover isn't clipped right. I would never leave the tub unclipped if I wasn't home however...
