How to re-connect this wire?

I am reconnecting a baseboard heater that was already disconnected when I moved in. One of the wires is no longer connected, but I can't figure out how to reattach it or what it's called. I'm including a picture on this post, it is the red wire at the bottom of the image. It is supposed to go on that black box in the only open slot of the 4 slots. Can anyone tell me what it's called or how to connect it? Doesn't seem to pop on or be screwed on in any way? Thank you.

I believe you will need to solder it on. Home Depot or similar stores will sell electrical repair solder. Something like this would work.

You will of course also need an electric soldering iron. And be sure the power to that circuit is off while you work on it. Care has to be exercised to not use any more heat than is necessary... you don't want to melt the plastic components around the connection, so you have to be very quick. You might need a second person to hold the connector down for you while you solder it.... and keep it down until the solder cools.

You could likely solder that connection if you have a good
soldering iron and reasonable soldering skills.
It is a permanent connection though and the thermostat should be replaced.

If it were me I would just go out and buy another one for the price of it.

That thermostat is around $10-$20, so I would buy a new one instead of trying to solder the old one.

I don't think you can even solder that connection. That is a riveted connection and the unit must be replaced and cannot be fixed (Unless you open it up and have the proper rivet gun and rivets, which would cost more to fix then to replace if you don't have the proper tools)

That connection runs too warm for solder..... unless you silver soldered it so I'm in consensus with replacing the thermostat.
