What is this thing called

Hi,

I am seaching for the name of this quick adjust thing:



Its used on a miter jig, an I have a similar "thing" on my tube grinder and saw it on some drill vise.
I was hoping to find a source but I have no idea for what to search.

Maybe one of you guys can help me.

Thanks Patrick
 

Not exactly sure, but there is a brand name "Grip-Master" fixture clamps that work like that.

Search for "quick grip vise."  That should get you in the ball-park.

Thanks thar brought me a spot further.
The Heinrich stuff looks quite what I am looking for.

Cheers Patrick
