The magnetic tape cassette is also provided with a sliding closure member slidably mounted on the bottom of the casing and cooperative with the aforementioned pivotal closure lid. The sliding closure member is in a closed position while the pivotal closure lid is in its closed position, in which it covers a bottom clearance through which a device constituting part of a tape holding system is inserted, and in an open position while the pivotal closure lid is in its open position to allow the aforementioned device of the tape handling system to reach into the casing through the bottom clearance. A locking pin holds the sliding closure in the current one of its two positions. The sliding closure holds the pivotal closed while in its own closed position.
