Quick release strap

[stratgod]

My uncle has this quick release strap thing on his strat and I can't find them anywhere. They are very similar to the type of clips you find on rucksacks and sports bags. I've heard them called cliplocks and straplocks but am at a lost point as it is a little annoying taking the strap off every time you want to put the guitar in case. Any help would be much appreciated as to where I can find one, bearing in mind I'm from England.
Cheers fellow guitarists!

Try some of these (http://www.stewmac.com/cgi-bin/hazel.cgi?action=SERVE&4=%2BSSC_LINK%3DStrap_Buttons&5=%2Bsort%3D1&ITEM=catalog/ssc.html). I use Dulop Straploks on all of my electrics.
