Abstract: The invention relates to a hook for hanging ornaments on a Christmas tree and is equally useful as an article supporting hook for lightweight objects such as necklaces, keychains, laminated cards and the like. The hook is provided with an article supporting portion and an integral circular portion with a depending locking leg portion. In use the hook is placed over a supporting member such as the twig of a tree as a supporting rod with the twig or rod inserted through an open portion of the circular portion. Then the locking leg is manually manipulated such that the horizontal portion of the locking leg is retained behind an upper portion of the article supporting portion and due to the resiliency of the hook the locking leg is continually closed. To release the hook from the supporting member the locking member is manipulated such that the locking leg is released from the upper portion of the article supporting portion permitting the hook to be removed therefrom.
