Discloses a quick coupler for use with a working machine. It comprises a coupler body with a first 14 and second 16 recesses for receiving attachment pins. There is a first 22 and second 24 locking member moveable between unlocked and locked positions for locking the attachment pins. An actuator 26 moves the first locking member between the unlocked and locked positions and a biasing arrangement 28 biases the first locking member into the locked position if the actuator fails. The biasing arrangement is configured to move the second locking member into the locked position as the first locking member is moved into the locked position. The maximum actuating force applied to the second locking member may be the actuation force of the biasing arrangement. The second locking member may be a clasp pivoted by a mover 48 that extends to the biasing arrangement.
