The cap extends at the distal end of the ferrule sleeve and is engageable over the coupling for tightening the coupling upon a hose faucet bib. The interior of the cap collar of the ferrule sleeve has a plurality of rigid equidistant distinct inner surfaces adapted to conform to the exterior surface of the hose coupling, when the hose coupling is engageable over the faucet bib, threaded portion. The longitudinally extending ferrule sleeve has a plurality of longitudinally extending outer surfaces to facilitate the manual griping of the ferrule sleeve by the whole hand of the user.
