pitlock sounds familiar... i should really pay more attention when the nice man in the bike shop waves things in front of my face and says "here thes are good, i'll fit them at the same time. better than plain bolts". basically its a little tool with a screwthread and a bolt which fits into a bolt-shaped hole on one side of the skewers. to take off the wheel you slide it in then tighten it and it grips it fairly hard allowing you to undo them/do them up very tight. theyre nice so long as you dont lose the tool.
