WHat would you use to repair the plastic sleeve that holds a fridge's
glass shelf in place?

This one seems to have been quite poorly designed, so the weight of the
shelf plus a bit of abuse has broken the plastic.

To make it worse, someone has tried to repair it with superglue, leaving
a pointless crusty mess on the plastic.

I have the feeling that the plastic area is too small to permit a repair
through bonding alone, and that I'm going to have to find some kind of
clip to hold it together.
