This is a replacement clip for a Snoo's baseplate.

This is a mockup of the bottom piece (see picture, purple clip), which surround the baseplate and keep it secured in (beneath the bedding insert). This piece fits quite well.

The used unit I bought had one of the small hooks broken off, so the top piece (see picture, white clip) would no longer stay in place. It seems only having one of these clips malfunction / break isn't that big of a deal, but looking at it, if more than 1 were to come off it will probably be a problem. I called their customer support team, and not only could they not provide a replacement, but I was told that the only way to get this 'fixed' was to order an entirely new unit. So, here we are :)
