Anyone have any idea as to what this might be used for?  It is a bracelet with a snap to attach the wire shown.  I have two of these and have no idea
what it might be unless its some torture device or part of a lie detector.

It appears to be a nicer quality wrist grounding strap, used so that you don't zap semiconductors with static electricity when you pick them up.  They are generally used in conjunction with a conductive mat of metal or impregnated rubber, and the whole mess is connected to real ground.  It is likely that the resistance from the bracelet to the plug is on the order of many many ohms, to bleed off static, but not connect you directly to ground in case you get too fat-fingered inside a hot chassis. 
I have one similar, but it's a cheap thing with a velcro fixed strap, not like yours with the way-cool Speidel TwistoFlex band.  Those were quite stylish back in the 60's.  If you play with semiconductors,  swap out processors in your computer etc, that rig is a keeper.

They got us those nice ones at Sony but neglected to order a variety of sizes or ask people to measure. therefore no large sized ones. Hope that one fits.
