Think they are Molex 1mm ZIF sockets.

Have a look at rswww.com (NOT www just type rswww.com into your browser) - enter 514-4521 into the search field and select RS Stock Number Search (this is the 26way)

I doubt that you will buy these in any electronics shop as they are a bit specialist but you can buy from RS if you have a trade account. May be a problem though in Belgium!

Hope this helps.

One thing that doesn't look too good from your photo though - the bottom of the two connectors - looks like the right hand latch clip is broken which may mean that the locking bar won't stay put.
