A theft prevention device for fixed-position tree stands employs a horizontal plate with ends bent over to engage a pair of upright supports of the tree stand. The plate has a hole at a central location through which a lag bolt extends, securing the plate to a tree. Barriers to access to the bolt along its length and at the bolt head are provided. A barrier underneath the plate takes the form of side plates connected to edges of both sides of the horizontal plate or a hub surrounding the bolt. An outside barrier protecting the bolt head is provided by a hub and a plug lock engaged with the hub.
