Mystery SwissGrip Spring Question

[ICanFixThat]

I recently purchased to WengerGrips / SwissGrips, a Red and a Black.  Nice!

However, I have a mystery that I'm sure someone can explain before I disassemble one of the tools.  Each of the tools came with the ''Spring'' just loose in the box.  I can't find anything in the instruction page on what it might be used for, I can only guess maybe so the Pliers will be spring loaded, but I can't find anyone mentioning anything about that.

Does any one know what this spring is used for?

It's meant to attach the bit driver extension to the plier handle.   (you DID get a bit driver extension....didn't you?)

Here's a stock pic from the Encyclopedia:





Admittedly, its not the most secure method for carrying the bit extension...

Thank You!

Yes I did get the Bit-Driver extension, but I NEVER would have guessed that's what the spring was for.  I figured one just stuffed it in the carry case with the bits.

I'm glad I asked, I just could not see it being put in the tool.

Yay, Bob to the rescue

it looks a bit out of place where it holds the bit though :/

That is a kooky way of holding the bit driver extension 
No wonder it is not unusual to find second hand SwissGrip's missing the bit extension tool
