ANTI-THEFT DEVICE FOR THE PREVENTION OF THE THEFT OF FUEL

摘要

An anti-theft device (30, 67) is provided for the prevention of the theft of fuel from a motor vehicle or other motor driven apparatus. The anti-theft device (30, 67) has a tubular member (31, 68) and a liquid permeable gauze barrier (34, 71). One end (33, 70) of the tubular member (31, 68) has an outer part (35, 72) adapted to receive a filler cap (16, 63) and an inner part (40, 74) adapted to engage a filler pipe (11, 60) with the tubular member (31, 68) extending along the pipe (11, 60). The tubular member (31, 68) also has engagement means (42, 76) operable on insertion of the device (30, 67) into a filler pipe (11, 60) to engage the filler pipe (11, 60) and resist disengagement therefrom. When the device (30, 67) is fitted to the filler pipe (11, 60), the tubular member (31, 68) extends along the pipe (11, 60) and is such a length that the barrier (34, 71) is far enough into the pipe (111, 60) to allow the insertion of the nozzle of a fuel dispensing pump but prevent the insertion of a siphon tube.
