ABSTRACT:
A device configured to form a sleeve having a proximal end, a distal end and an elongate body portion having an axial lumen therebetween. The body portion is dimensioned to accommodate a length of hose within its axial lumen. The proximal end of the device has a wrench portion adapted to matingly engage at least a portion of the outer surface of a female threaded coupling fixture mounted on a terminal end of the hose. The distal end of the device may or may not be flared outwardly to prevent the hose from kinking when the female coupling fixture mounted on the hose is attached to a supply source such as a water tap. The body portion and distal end of the device is adapted to rotate freely about a length of hose housed therewithin. In one embodiment, the proximal end of the device has a stop operable for preventing the device from sliding away from the female coupling fixture mounted on the hose. The body portion of the device is adapted to prevent the length of hose housed therewithin from kinking along its length. Between the device's proximal end, which in operation overlies at least a portion of the female coupling fixture, and its distal end, the device provides grasping means operable for applying torque to the female coupling fixture enabling a person to comfortably and easily rotate the rotatable female coupling fixture on the hose to facilitate threaded attachment to or removal from a mating fixture or supply source.
