Instead of a chain, there is a piece of wood with a pin on each end. One pin (which attaches to the horn) has female threads, so I'm assuming there is a cap or a screw that goes in there to secure it. However, the pin that attaches to the crane is just... a pin that slips into a hole in the crane. If somebody bumped into this thing, the horn and wood piece would come crashing down, probably snapping the neck off the reproducer! I guess you could wrap it with wire or something like that, in order to secure it.
