Zusammenfassung:	A high-security fill cap is adapted for releasable attachment to the open end of a fill pipe, connected to an underground fuel storage tank or the like. The fill cap comprises an annular cap, a plurality of latches pivotally mounted on the cap for movement between latched positions engaging the pipe and unlatched positions disengaging the pipe, an actuating mechanism, including a handle, for moving the latches between their latched and unlatched positions in response to reciprocal movement of the handle, and a key lock secured centrally within the handle to selectively rotate a cam plate thereof between its locked and unlocked positions beneath the cap.
