Weaned calf having a sly sook

[choochter]

Got a weaned calf that still wants to suck. Have removed his mum who has another calf now but I see today he's managing to get a sook off another cow. Where do you get that gadget that goes on their nose? What's the name of it? And is it easy to fit? Any other suggestions, although can't move him to any other group just now.
