Thermistor Location?

I have taken the extruder off to clean it thoroughly and am just about to reassemble it. However, I just want to check on exactly how to replace it. Does the grub screw clamp against the actual thermistor element, or should I push the thermistor past the grub screw and clamp the screw onto the cable? I'm pretty sure it should grip the thermistor itself, but want to check before I do it.
