This disclosure relates to a tear-away tab or closure for cans, in which, the tear-away closure is retained on the can. The top of the can is formed with a tab defined by a scored segment extending radially from approximately the center of the top to the rim of the can. A stem overlying the tab is secured to the inner end of the tab and extends along the tab towards the rim of the can. A pulling ring overlies the stem and is secured to the outer end of the stem. The can is opened by lifting the ring upwardly and pulling the stem to a generally vertical position over the inner end of the tab, then forcing the stem and ring downwardly so that the tab will break away from the can top along the scored edges to form the opening in the can. The outer end of the tab is not scored, and thus remains attached to the top when the can is opened.
