Abstract: A coupler for an excavator or other apparatus comprising a body for receiving an excavator attachment; a first latch member movable into and out of a latching state in which it is capable of retaining the attachment on the body. The first latch member being movable into and out of the latching state by an actuator, wherein a gravity operated valve is associated with the actuator. The valve has a first state wherein fluid can flow through the valve as the latch member is moved out of its latching state, and a second state, wherein fluid is prevented from flowing through the valve thus preventing operation of the actuator to move the latch member out of its latching state. The valve is adapted to adopt the first state when the coupler is in a non-working orientation and the second state when the coupling is in a working orientation.
