A banknote cassette advantageously uses injection molded endcaps to capture and secure a connecting sleeve to collectively form a generally rectangular housing of the banknote cassette. A movable access lid cooperates with the endcaps and connecting sleeve for locking of the cassette. Preferably, a banknote slot is formed as part of one of the endcaps to provide precision in the size of position of the banknote slot. The endcaps can be used with different sized connecting sleeves to simplify the manufacture of different capacity banknote cassettes. Preferably, the connecting sleeve is of a metal material.
