A resealable can end closure assembly comprising:

• a cylindrical can body having an open end and a closure engaging finish extending around the exterior surface of the can body adjacent the open end;
• a cylindrical closure having a depending peripheral skirt for operatively engaging said finish;
• a set of first type spaced knuckles on said finish, said first type knuckles having respective inclined surfaces on undersides thereof;
• a first plurality of inwardly projecting spaced fingers on said skirt for engaging the inclined underside surfaces on the set of first type spaced knuckles when the closure is tightly secured to the open end by the rotation of said skirt on the finish in a closing direction, said first plurality of fingers releasing from the knuckles in response to rotation of said closure in an opening direction;
• a set of second type spaced knuckles disposed on the finish of the can below said set of first type knuckles;
• said closure additionally including a pilfer-proof ring detachably secured to the bottom of said skirt by a frangible perforation, said pilfer-proof ring having an inwardly projecting second plurality of spaced fingers for engaging said set of second type knuckles for preventing removal of said ring from the can body when said closure is first secured to the open end of the can body;
• and
• a relatively thin holding strap of flexible material connecting the pilfer-proof ring to the skirt and located within a rectangular aperture formed in the skirt so as to maintain a connection between the skirt and ring when the frangible perforation is broken.
