They're spring toggles you find on pretty much any non-waterproof stuffsack.  Any reputable camping supply store should have a bulk bin full of them if they have bulk bins at all.

They're not really.  I picked up some of the ones they have at MEC (and they do have a bulk bin) and they're pretty cheap and in fact won't really hold the laces without slippage.  I tried them out and I don't have confidence that they'll work.   I think the ones ST is talking about, at least according to his description, are better quality that will properly bite down and do the job.  My problem is how do you order something worth $2.50 when shipping is $20.
