Heavy chewer recommendations!?

I have a 12 week old Great Pyrenees/Anatolian Shepherd mix. I bought him a product called fursicle it is similar to the woof pupsicle however he can get it open in less than 10 minutes.

Has anyone used the woof pupsicle with a very heavy chewer and is it secure where it screws together?

Or have recommendations for a similar product for heavy chewers
