Lost Apple TV remote loop tie part

unfortunately, I have lost the little part it my Apple TV remote which allows you to tighten the band around your wrist (see images below) I’ve turned the entire house upside down and still can’t find it :( I’ve come to believe that it’s gotten caught up in the hoover or something. It’s driving my ocd mad and I know it’s only a small thing but I’d like to get a replacement if I can. Anyone know where I can find one of these parts? The remote is a bit loose without one (I’m in the uk by the way) Thanks, Alex
