What is this part (banana short tab?) called?

[reynaldogonzalez]

I would like to purchase some extra of these parts but I'm not sure what they are called/how to search for them.
It is the small metal tab used to connect negative terminal to ground terminal on power supplies.

Not sure if there is an official name, but "Shorting bar" should get you something.  Pomona 4115 looks like the correct item.

Try 'shorting link' - https://www.alliedelec.com/product/pomona-electronics/4115/70198108/

Thank you for replies!

I was looking for some of those shorting links a year or so ago and found they seemed to be very, very expensive for such a small simple piece of metal. Searching around I found where someone recommended a site where you could get 10 for $3 but the minimum shipping was $9.90.  I ordered 30 for $9 plus shipping and got a lifetime supply for under $20. That's still far better than the previously mentioned source where you's pay $36 per 10 and shipping on top of that. I'm always picking up some piece of equipment where the links are missing so I'll have them if I need them

Why buy them at all?   

I just make them out of 2.5mm² solid core wire, as and when I need them.

You can replace a broken exhaust hanger on your car with a bent wire coat hanger but some of us take more pride in our equipment.

Thanks for the tip, AD!  I'd bought a few over the years from Mouser (Pomona 4115), but they were quite $$ for what they are - currently $3.70 a pop!!  I just took your lead and bought three 10 packs - should keep me in them for the foreseeable future assuming I don't lose them in the meantime.  Sure, you can do it with a wire, but then if you disconnect it the wire's apt to get lost and then you'll need to make up another one next time.  These can just slide off to the side and be left to dangle, or clamped down, and will stay with whatever they're on.  Much more convenient IMO

It seems you got the answer to what it called.
Anyway, it sounds like "knob"

That doesn't sound very durable, though certainly if it gets you out of a tight spot it seems a legit temporary repair.

Pride? I prefer functionality, and practicality. When I come to repair old gear I buy, I never spend more than I have to.
I only clean things if it's either a hygiene or a functional impairment issue.
I know many like to restore things to factory fresh appearance, and that's fine, but I like to see the history of the thing; cal labels, small dents and scratches that don't spoil functionality are fine by me.
