Abstract: A camera back having a frame for receiving a camera component and a locking arm pivotally connected to the frame. The locking arm includes an engagement surface for holding the camera component securely to the frame. The locking arm comprises a top and bottom locking member pivotally mounted to the frame with a handle connecting the top and bottom locking members. A biasing element urges the engagement surface against the frame in a downward position to securely hold the camera component in the frame. A tension device is attached to the frame so that after the camera component is locked into place on the camera back, the tension device effectively holds the locking arm in one position to avoid inadvertent unlocking.
