Not familiar with these precise connectors, but if the connectors are like previous ones, you can normally unhook the plastic fairly easily and switch to a longer cable - this is assuming they aren't anchored permanently at one end.
If you don't want to adjust the supplied clips, maybe contact your local service centre and see if you can buy a set of the connectors? I don't know how much they would charge, but can't imagine they would be expensive..
Hope this helps
