Abstract: A ring to which things can be tied, hooked or otherwise linked is pivotally affixed to the end of an elongated shank. At the opposite end of the shank is a wide hook, preferably as wide as the connecting ring. Integral with the shank is a leaf member which protrudes into the hollow of the hook. The leaf member and tongue of the hook are biased toward each other. The hook is used to catch a rigid planar lip of a structure. The biasing causes the lip to be clamped between the leaf member and hook tongue to hold the device in place. The hook is oriented so that any tension applied to the connecting ring is counteracted by force against by the hook by the rigid planar lip. Things connected to the ring are thereby anchored by the structure.
