That looks like a shoe for concrete form.slides onto a snaptie to hold form panel in place but i could be wrong.

That makes sense. It looked to me like it would capture a rod with a ball on one end and maybe also a groove. Sort of like a hand-pump grease gun for your car. To change the grease tube, you pulled up on the handle till the groove in the rod could be caught in the narrow part of the end plate. This compressed and withdrew the spring so you could change out the empty grease tube. Lots of similar low-tech locking/catching applications come to mind.
