I am cleaning the electrical plugs and found heavy corrosion, plus a broken contact ( I think ). I do not think they come apart without breaking them?
I would like to replace both, but if I cut the wire it will not reach. Would I just break them apart? Not sure if I can use different plugs of the same type.
I am doing this now.

There is a thin stainless springy tab under each of the contacts.  You can see the edge of the tab in one of your pictures.  Slide a small screwdriver between the tab and the contact and it unlocks the contact.  Just slide the wire and contact out of the plastic housing.  It takes a little fiddling but is easy after you do a couple.

Thanks! I just figured it out. Easy fix.

Thanks for the instruction George, I was out all day and wasn't around the computer.

Once out just use a wire brush to clean them, they are soldered to the cable so replacing shouldn't be necessary. Just a good cleaning. Just be sure they go back in the right orientation and position.
