A locking assembly for securing spools of fibrous material on a spindle during a pressurized dyeing operation. The locking assembly has jaws which, when in a locked position, engage with the spindle to secure the spools thereon. An actuator moves the jaws to a released position for removal of the spools. A tapered surface of the jaws cooperates with the spindle to allow the locking assembly to be placed on the spindle without the need for manually setting the jaws in a released state.
