Abstract

Abstract The invention relates to locking device for locking caps upon the filling necks of tanks, the primary use being for securing the caps of motor vehicle gas tanks in place to prevent theft of fuel. It is a locking device consisting of a cylindrical body member, having a cup-like form, terminating in a two-part inwardly extending collar. The device is designed so that the inwardly extending collar portion may bypass the tank cap as the device is installed or removed and yet be locked so as to prevent installation or removal. The two inwardly extending collar members are disposed in overlaying relationship and held together on one end by means of a rivet so as to render one collar member pivotally movable, both having on their opposite ends an aligned aperture to register affording passage of the shackle of a suitable locking mechanism therethrough. With the device in locked position, locking a cap upon the filling neck of a tank, and the shackle of a locking mechanism in said registering apertures, the shackle is holding also the end of a flexible, theftproof ligament connecting the lock mechanism to a part of the vehicle body other than the over-all locking device, substantially as and for the purpose herein set forth.
