On this pump motor the yellow wire (next to the 3) broke off. I am unfamiliar with the connection. Do I need a special tool to reattach this (after I strip the wire)

@Jeffery obviously it is broke but it didn’t look like it but I don’t know where it’s broke do you have a soldering iron and some solder ?

Megawatt, yeah it broke just below the contact. I was wondering if someone here was familiar with the type of connection. I haven't had need for a soldering iron but if that's what is required I guess I can try. If you zoom in on the connection it looks like there's some teeth that could pull apart. I didn't want to try this with a needle nose and risk breaking the connection point.

it looks like they were originally crimped into the terminals,
Sometimes if your carefull you can gently pry the terminals apart and re-use,
but it is very fiddly work and you are DIY so it will be difficult
Soldering is another option, but if you have not sodered before
Then you will likely end up with a mess.
Get someone who can solder to do it.

It was a factory crimped connection on the Klixon and you're probably going to cause collateral damage if you try to pry it open and resqueeze it. As mentioned above your best bet is probably solder. If you've got no soldering experience take it to a friend who has, it won't be particularly easy to get a good solder joint because the contact on the klixon will sink a lot of heat compared to the wire you're soldering to it which makes things a bit trickier.

Looking at terminals 1 & 2 especially, it seems like the cable end was ferruled and then spot-welded to the Klixon tag. Curiously terminal 3 looks different, but the remedy as mentioned above is probably to solder it. Take care not to cook the tag in the process!

Sorry, OP, an alligator clip is not a safe, permanent solution. It could so easily cause a ground fault that it doesn't bear looking at. Please consider reworking with a soldered connection.
