Abstract
A locking apparatus attaches a key to a writing instrument. The locking apparatus comprises a barrel having a top end and a bottom end. The top end has a top opening with a first diameter. The second end is attached to the writing instrument. A bore extends inwardly from the top opening. The bore has a second diameter which is larger than the first diameter. A step is formed in the barrel at top of the bore. A post has an upper section and a lower section. The lower section is slidably engaged in the bore. A plurality of tabs is pivotally connected to the lower section of the post. The tabs extend outwardly from the post so that tabs impinge the step. A ring is slidably supported in the bore. The ring has a center hole adapted to frictionally engage the tabs for removing the post from the barrel. A key is connected to the upper section of the post.
