I think my heat bed thermistor is broken (infinite resistance measured) on my Prusa MK2, so I bought a new one, and I'd like to know which connector I shall use. Where can I find the references of this connector, please ?
Regards,

The thermistor is just a resistor. Polarity doesn't matter. Connect it wherever the old one was connected. Typically it connects to a pair of male pins on a RAMPS board, so a 2-pin female connector with standard 2.54 mm (0.1") pin spacing is called for, unless your printer uses a different board.
For a visual reference, look at the extruder RTD connection on your printer.

Those are JST SYP 2 pins female.
