The TE-band (3) of a closure cap for closure of a container is provided with retaining elements (5) which protrude radially inwards and upwards to the base of the closure cap from the inner surface of the TE-bank (3). Each retaining element (5) comprises a retaining surface (6) terminating in a retaining edge (7). The retaining edges engage beneath an engagement surface (10) on the mouth of a container when the closure cap is in position on said container. The retaining edge (7) are formed as a concave segment and all retaining edges (7) together define substantially a circle. The circle is coaxial with the engagement surface of a container mouth and has a diameter which is smaller than the outer diameter of the engagement surface of the container mouth.
