Sometimes there isn't enough room for a decent size lynchpin so they use 'R' clips. The bigger ones that your finger fits in are Ok but the tiny ones are a bear to get in and out sometimes.
I modified an old pair of pliers by drilling a hole near the end and they work so well I'm posting it.

Fits larger ones too
