A deck box for a marine vessel having a deck provided with an opening for accommodating the deck box, the deck box comprising:a cylindrical housing adapted to be mounted within the deck opening, the upper end of the housing being open to provide access to operation mechanism within the housing,a circular cover for closing the open upper end of the housing, andmeans for securing the cover within the housing, the securing means including:a locking tongue carried by the cover, the tongue being spaced beneath the lower face of the cover and projecting in a radial direction, and the tongue having a circumferential length less than 360.degree., andan arcuate groove located within the housing, the groove extending for less than the full circumference of the housing interior, the groove having a tongue-entry end and a tongue-locking end, the locking end of the groove cooperating with the tongue to limit rotation of the tongue to less than 360.degree., and the groove having a downwardly facing cam surface which is inclined downwardly from the entry end toward the locking end of the groove,whereby when the cover is inserted into the housing with the locking tongue at the entry end of the groove, rotation of the tongue causes it to slide along the cam surface of the groove and draw the cover downwardly into the housing.
