I am sorry i don`t know the exact translation of it. This connectors are standardized components for electronics. They are called "Kabelschuh" in germany and
http://dict.leo.org translates it to "cable socket/cable shoe/cable lug..." which sounds right to me.
Well you just have to remove the insulation of each single cable just like you would to solder them. The blank wires will conduct with the iron of this connectors. You put the wires into the pipe and you can either use a gripper to press the plastic end together,
or you can also solder it, without the risk to destroy your daughtercard if you are not familiar with soldering (like me).
And finally you can shrink the plastic by heaten it carefully and fix it to the isolation of the cables.
As i mentioned above i bought the wrong size (0,75mm2) and all i did was press it together on each side. For conduction and to keep the cables in place. I´ll make a quick sketch and add it later.
btw sry for my bad english ^^
