Improvements in closure elements prepared to be detachably attached to a container, characterized in that they comprise a substantially cylindrical bushing comprising an end wall and a side wall; a substantially cylindrical retaining ring that forms a body with said bushing and holds it on the lower edge of the side wall; a weakened union, between the bushing and the ring; a series of extended grooves substantially parallel to the axis of the retaining ring, arranged around the periphery of said ring; said grooves function to fit in ribs of the container, and prevent rotation of said ring with respect to the container; the side wall of the bushing can be deformed in adjustment with a thread of the container, so that when rotating the bushing with respect to the container, the retaining ring separates from the aforementioned bushing, in the indicated connection.
