I'm looking for the correct terminology of the connector in the pictures below, which, as far as I understand, serves to connect unstriped wires pretty easily to some form of socket. I encountered it in a washing machine. I tried googling and going through a distributor's online catalog, but I'm not getting far without the correct jargon.
The first two pictures show the connector opened up. The metal pieces serve as both connection pin for the socket and to pierce trough the protective layer of the wires which have to be pushed trough the top holes. I suspect that first the wires are pushed trough the holes, then the metal pins are placed, and finally the whole is closed.
The last two pictures show the connector when assembled.
Edit:
To further clarify the use of the connector. It is used on the thermostat / thermistor of the the dryer in the machine.
one side has a latching tang
use a knife to lift the retaining tang
like so
then the wire slides out of the housing

The technology is called Insulation Displacing Connector Technology
An insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor(s) of an insulated cable by a connection process which forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the conductors of insulation before connecting.

To further narrow down, measure the pitch, estimate AWG (it may be printed on the red cables), try looking for markings on the connector (some markings are molded with the connector having the same material/colour: changing the incidence of light may make it more clear)
