Found it in my sex draw stretcher things and they have two hoops at the ends of them and a clip and a clip at the bottom with an extender ? I can send a pic if that would help

** moved to lingerie and clothing**
As this is not a sex toy.. it is a bra strap... A clear one so that strapless tops/ dresses etc may be worn 
Hope that helps clarify
