wiper arms...what the @#$%
 

So, I went out to clear off the 10" of snow, and not only 1, but BOTH wiper blades FELL OFF...

One broke into pieces, the other won't go back on..
The end of the arm doesn't seem to match any pictures I see online..
Here's what both arm ends look like:

Is it me, or am I missing....something that would clip into a wiper blade..?

Help!

Thanks,
Rich
