The lock includes an elongate band of synthetic resin operatively associated with and circumferentially surrounding the top wall with opposite ends spaced apart and having radially inwardly projecting securing structure receivable in the recess for securing the top wall to the container. A locking structure is provided for constricting the spaced ends of the band to urge the securing structure radially inwardly comprising a pair of radially out-turned tabs of a high-strength synthetic resin secured to opposite end portions of the band as by vibration welding. A locking lever is movable to an over center position for adjustably drawing the tabs toward each other and releasably locking the securing structure in the annular recess in the over center position.
