Need help identifying lighting wire connection

I am trying to fix a light at work for our big marketing show booth. One of the wires that connects to the power supply is missing the pole inside of it. Broken off and fallen out. I do not know where to begin looking for a replacement part and could use some help. I don't know what the piece is called to then begin looking...

These are the pieces to connect:

Here is a pic showing the broken piece (Left - pole missing inside) next to one that is not broken:

This is the male and broken pole female piece:

Thank you,

if Dc power the red is the hot and black return. Red wire should be center conductor. Black wire should be outer. You can check by toning with meter.

There are also kits that have tons of various adaptors, where it's probably that one would work. Only would need to find rating etc.

Couldn't say which one you would beed precisely. Just a option if you can’t identify the type needed. And Amazon offers free retuns if you did a visual it could fit to one or two kits. Not sure this would work in your case but it's a extra option if the other suggestions don't work. A adaptor could pair with another wire harness if you can’t match up the ends Is specifically what I'm refering to.
 
300v 18awg. With a magnifying glace I was able to read it off the wire. Got a 10 pack of male & female for 9 bucks.
Things to look for when buying/setting up DC plugs:
  • Gauge of the wire: limits the amps and voltage you can safely use (and the wattage which is for derivable from those). Eg 18awg. If you buy too weak a gauge (a bigger number) you can melt the wires and set yourself up for a short-circuit
  • The size: Randy's picture is the standard size, 2.1x5.5, which is the size of the tip. Higher rated things tend to have bigger ones. If you get the wrong ones you can buy adapters or better yet just but the right ones
  • Polarity: whether you want the power to be on the center pin or the outside. Both are valid options, and there's a little icon which says which a device expects. You control this by how you wire it; plugs can work either way. Make sure you test it out with a multimeter to ensure you get the same setup before and after. If not, you will likely produce the magic blue smoke as the spirit of the electronic device moves on to the afterlife
Also some DC plugs are total crap and fall apart from minimal usage. You can't really tell until it arrives in my experience.
