What is the thingie on the WBT Bananna Plug


I am looking at getting some bananna plugs, and in particular have noticed the WBT model 0645. It looks like it has an insulator or something plastic that protrudes from the front parallel to the bananna extrusion. Anyone know what this is? Looks like this will prevent the bananna portion from going into the receptacle, will it?

Also, any comments on this plug, where to get it, or other comparable connectors. Please, Bananna only because that is all my speakers will take, the have 4 bananna holes per speaker (no "spades are better" please because I can't use them).
Here is the wbt cite

Thanks in advance for your helpful comments and/or jokes!

Gunbei, you have got it right, and Motorpsychos I think has the solution I was thinking of, its good to see people with the same problem at least. No reason performance wise not to cut the plastic dealie off and use it anyway.
Yes, I am referring to the angled plugs. See the situation is that my speakers have 4 flush holes in the center of the rear of the speaker for biwiring with bannanas, they do NOT have binding posts. So if that plastic dealie is designed to hit or engage the outer periphery of a binding post to prevent rotation of the plug, it will likely prevent the bananna from being inserted into my speakers, right? At least this is how it looks from the picture. Do you get what I am saying?
Well, my "problem" is the same as everyone else here, wanting this stuff in the first place, so I don't know if that's fixed. But seriously, thanks to everyone for the assistance.
