The disclosed invention relates to maintaining a closed and secured position of a tank fill port cap on a tank such as a fuel tank. The invention comprises a dual collar structure providing a means for the attachment of a lockable blocking device to prevent a tank fill port cap from being removed from a tank fill port nipple. The lockable blocking device is removably and securely installed on a first collar and wherein the first collar is removably and securely installed on a tank fill port nipple such as on a large commercial truck fuel tank. The first collar and the blocking device discourages or prevents the theft or vandalism of the contents of the tank. The first collar attaches to the tank fill port nipple with setscrews in a continuous one piece collar or a clamp screw in a clamping split collar configuration. A second collar is fitted over the first collar covering the first collar attachment means preventing tampering or removal of the first collar. The second collar is secured in position by the blocking device being attached to the first collar requiring the blocking device to be removed from the first collar in order to remove the second collar from the first collar, therefore, maintaining a secure and removable dual collar device locking device to secure and protect the contents of a tank by preventing the tank cap from being removed. In addition, the lockable blocking device is required to reside in a position that does not interfere with a tank pressure relief device that may be centered in the fill port cap.
