Looking for speaker post jumper cable (!)

In a nutshell: A cheap* pair of jumpers (below 10k) is what I am looking for and so any recommendations or pointers would be appreciated. Must be spades --> banana.

I may be using incorrect terminology but I am looking for a pair of "jumper cables" to connect the HF-LF terminals at my speaker's binding post. I believe this page illustrates the type of product I am referring to:

I have a low-end speaker* with no doubt a cheap brass bar so I hope I can expect some improvement by replacing the same with high quality cables?

I understand the quickest solution is to snip off some speaker cable and use the same to do the trick. Problem is, my speaker cable (Solitone Model X) is factory terminated and I don't want to mess with it.

(* - this is what the asterisks are about: The upgrade bug is visiting again so I don't know how long I'll have these speakers. So spending a higher amount seems a waste if my next pair of speakers won't support or require bi-wiring.)
