ABSTRACT:
A locking device for tank filler tubes is described, comprising a sleeve member for insertion in the filler tube to provide smooth walls, and an annular shaped locking collar that slides inside the sleeve and fastens through the sleeve to the inside wall of the filler tube. The locking collar does not have to be removed in order to fill the tank. Two disks, having off-center openings large enough for a filler hose nozzle, are arranged one above the other in the top of the locking collar so that the top disk can be rotated to allow the off-center openings to be aligned for a filler nozzle. A cylinder lock prevents rotation of the top disk when in the locked position. An alternative embodiment of the invention does not fit inside the tank filler tube, but rather is welded or joined to it. This alternative uses a padlock which prevents a cap from being rotated to a position which aligns openings in the device, allowing insertion of a filler hose nozzle.
