A line handling device designed to facilitate positioning and handling of a mooring or docking line during a boat docking operation is removably mounted on an extendable pole, such as a boat hook. The device has an elongated body with a tapered end. A longitudinal groove is formed in the body to accommodate the shaft of the boat hook. A flexible resilient fastener is attached to the body and encircles the shaft of the boat hook. A docking line may be wedged between the clip and the shaft of the boat hook to form a loop to engage a piling.
