Hi guys, the other day, cleaning my 190, i've discovered this connector under the front passenger floormat, anybody knows for what is this connector?

hard to say, since on certain years there's quite a few connectors on the passenger side (Engine Check reset, O2 sensor wires, etc.) but it could be the wire to the seat belt warning system which connects to the seatbelt buckle.

It's the oxygen sensor. The green single is the signal and the other two are the heater leads.

MBDOC is right, I didn't see that the plastic clip and the single sensor lead were connected. The O2 sensor is part of the fuel injection and emission system. With the O2 sensor disconnected or "out of the loop", after the car warms up (when the sensor would be getting to operating temperature0 you probably are getting bad gas milage and fouling the spark plugs with excess gas being sent to the cylinders.
