Abstract
A magnetic tape cassette of two half cases. A locking member is slidable backwards to lock the hubs holding the tape. The locking member is biased by a spring fixed to a protrusion at the front of one of the half cases. Backward facing legs of the springs slidably engage a lateral recess in the locking member to bias it backwards against the hubs.
