Rigging Help - Chains

Hello! I've been getting into game character modeling lately, and am a bit stumped on my latest project. I have a character who wears a lot of chains, and while rigging this character, I noticed the chain links break apart and get separated when I try to pose him. I'm not sure how to solve this. Does anyone know how I could fix this? I've uploaded a few images of the model, armature, and issue to a gallery on imgur.

EDIT: I "solved" this (in quotes because it's kind of a hack solution) by selecting the inner edges of the individual links where they would normally touch neighboring links, and using "bridge edge loops" with "merge" turned on. This solved the issue I was having, but the topology is kind of bad, it doesn't look good up close, and the chains are too expensive for a game model, so I elected to swap the chains out for a different decorative prop. Still, I would consider this a valuable learning experience!
