A latch for the door of a tape cassette includes a latching member for latching the door closed. The latching member is mounted for rotation about an axis between latching and unlatching positions. A spring, including a resilient arm, urges the latching member toward the latching position. One end of the arm is formed in integral, one-piece relationship to the latching member and the opposite end of the arm is free, but bears against a wall in one of the cassette housing halves on the side of the latching member in the direction of rotation toward the unlatching direction. In one embodiment of latch, the end of the arm which is attached to the latching member is located between the axis of rotation and the opposite free end of the arm. In a second embodiment of latch, the end of the arm which is attached to the latching member is spaced from the axis of rotation and the opposite free end of the arm is between and nearer the axis of rotation than to the attached end and bears slidably against a wall in the cassette. In the latter embodiment, the arm is attached to the latching member by torsion members formed integrally with the latching member and arm to form springs.
