They lock. Might need to look at a video if you have trouble with it. But they do. There are a couple nubs on the attaching point on the metal (the trapezoid plate) that creates friction and sort of 'hook' onto the black inner area of the Fin Funnels, after lifting the dark gray flap on the funnel all the way, and the metal trapezoid plate sit snug all the way into the spring-loaded slot. Decently secure once its all the way in. Won't fall even if you shake it or wiggle the funnels individually, and needs to pull at a certain angle to release it. Use the small side hooks on each funnel to make the whole assembly even more secure, in case one or more of the metal attachment is loose, you still have the others to help holding the loose ones in place. And I find it easiest to have the whole rack of fin funnels assembled on the metal attachment piece first, before putting on the backpack. If you have 2 sets and doing the double fin funnel look, follow the instruction order on the left set in the manual, going funnel 1, then 2, then 3,4,5 & 6. But on Nu's right set, reverse the order putting onto the metal attachment, going 6 on the far end first, then 5, 4, 3, 2, and 1 working towards the center. The reverse order makes it much easier to use the small side hooks, without having them getting in the way and scratch up the funnels while you struggling with them. They didn't teach any of the reverse order in the manual unfortunately. Hope this helps.
