The closure plug (1) has an elastic clamping sleeve (16) fastened to an inner side (13) of a sealing cap disk (14). The sleeve has an annular locking element (18) radially protruded into the cavity to lock the sleeve with a ring segment-like counter-locking element (19). Outer diameter (D1) of the locking element is approximately equal to diameter (D2) of a cylinder segment-like inner wall (21) such that the locking element at an inner end (17) of the sleeve is guided before locking with the counter-locking element by the inner wall during fixing a sealing cap (5) on a bung-hole plug (4). |
