Clasp on leather work gloves?

[GeorgeLang]

Greetings all!  I wonder if anyone might be able to help me identify a piece of hardware.  It's the small (1/2") round double-slotted metal clasp used on ball and tape wrist closures on work gloves.  It has 4 teeth used to attach to the leather.  I thought at first it was a concho, but most conchos are not this small (at least, not that I can find), nor do they have the required teeth.  Any help identifying or locating this piece would be greatly appreciated.

Thanks very much -
