I've been running through my head if it's possible to make an X-shaped dogbone that can actually not pull apart. I have an idea about a tarp system for my annual camping trip with some friends, but need something like an X-shaped dogbone to tie them together. It would look like an old lug-wrench.

If I just feed one through the other, it can't really distribute load to the perpendicular legs. If I make two L-shapes from the two pieces, it seems like it would be kind of week. Anyone have an idea of how I could do this? I don't want to resort to just a ring, or continuous loop. Partially for aesthetic reasons, and partially because I just want to make an X-shaped dogbone. A 3-legged dogbone might also work, if anyone has an idea on that.
