In the locking position of the pin, in which the pin is received through the aligned openings, a transverse hole in the lower end portion of the pin is aligned with a vertically elongated slot in a wall of the bracket for receiving a security member to prevent upward movement of the pin out of the openings.

A cam member pivots between pin blocking and pin releasing positions and has a flat lower flange with a vertical hole therethrough. The hasp has a flat upper wall with a hole therethrough aligned with the hole in the cam member lower flange for receiving a security member to prevent movement of the cam member from its pin blocking position to its pin releasing position.
