A pouring cap for mounting atop a neck of a container is unitarily formed of a synthetic resin with a body adapted to fit over the neck of the container and having an outer body edge centered on an axis, a central pour tube within the edge and forming an axially throughgoing outflow passage, and a cover sealingly engageable in a closed position with the body over the passage at the edge. A hinge is provided on the edge between the body and the cover and a hook projects axially from the cover in the closed position past the edge of the body at a location on the edge generally diametrically opposite the hinge. A retaining element defines with the body an opening adjacent the edge opposite the hinge location. The hook is engageable with elastic deformation through the opening to catch underneath the retaining element and once inserted through the opening is engaged such that the hook or the element must be permanently deformed to move the cover from the closed position. Thus the hook and element retain the cover in the closed position until the element is stripped from the body. Frangible connecting webs flanking the opening connect the retaining element to the body.
