They are held on with an odd three sided square type circlip.
You need a steady hand, a tiny thin flat screwdriver and a magnet handy in case it pings away!
if you look carefully the connector goes over the top of the injector, you need to prise the clip away on two edges and then remove the plug/connector.
Its a idea to apply a little pressure to the plug (as though you are trying to put it on) this takes the strain off the circlip.
