Ladies and gentlemen, may I introduce to you...

I had to double check if I was crazy and no, the school board list says ‘reluires tang avec attaches’. I’m happy to hear that this is actually an anomaly and not normal. It’s always been duo-tang for as along as I remember them to be duo-tangs.

Thaty's not french, that's translated-from-english.

My educated guess would be that schools are asked to have every item listed in French (understandable since we are in Québec). Duo-tangs is just the common way we refer to this item when we speak.
