A locking mechanism for a horizontally swinging gate bar, for locking the end of the bar to a vertical post. The vertical post has a cap member threadedly mounted eccentrically thereon, said cap member having a cavity to receive the end of the gate bar. The cap member contains a locked linkage, one of whose links includes a locking projection engaging in a slot in the post, whereby to lock the cap member in a non-rotatably held condition lockingly receiving the end of the gate bar. The linkage includes pivotal connections formed by the shackles of padlocks. By removing at least one of the padlocks the linkage can be disconnected to allow withdrawal of the locking projection from the post slot, to thereby allow the cap member to be rotated sufficiently to enable the end of the gate bar to be swung out of the locking cavity. A stop member depending from the floor of the cavity cooperates with a horizontal lug in the post to prevent unscrewing of the cap member from the post.
