A security cap for the fuel filling conduit of a motor vehicle, the fuel filling conduit having an inwardly directed flange surrounding a non-circular opening, said security cap comprising a body (110) having a flange (110a) presenting a downwardly facing surface (110j), a tang (110c) depending from said flange, cam surface means (110h) projecting downwardly from said tang, and an opening (110e) extending through said flange and tang, a lock cylinder (111) within said opening and having an extension (111b, 111c) extending below the bottom of said tang, said cylinder being rotatable within said opening through a limited angle between an open position in which the cap is removable from the filling conduit and a closed position in which the cap is not removable, an elongated latch (114) carried by said cylinder extension and rotatable therewith about the same axis, said latch being axially aligned with said body flange surface, and said latch fitting through the opening in the filling conduit flange when in one position of rotation corresponding to the open position of said cylinder and said latch not fitting through that opening in another position of rotation corresponding to the closed position of said cylinder, the filling conduit flange being gripped between said latch and said body flange when said cylinder is in its closed position, and said latch being movable axially of said extension, spring means (115) urging said latch axially of said extension toward said flange, and follower tooth means (114b) projecting upwardly from said latch and cooperable with said cam surface means for moving said latch axially away from said flange surface, against the force of said spring means, during rotation of said locking cylinder and latch between said open and closed positions of said cylinder so as to reduce the frictional engagement between said latch and the filling conduit flange during rotation of said latch between its positions of rotation corresponding to the closed and open positions of said lock cylinder.
