The capsule comprises a tubular sleeve (18), smooth on the inside, gripping the head (2b) of a plug (2) with which a handle (3) is associated by means of two diametrically opposite pivots (3a, 3b). The sleeve is provided with notches (19) which are open upwards in order to receive the pivots, whilst the teeth (22) of the ring (20) interact with the outer catches (13) of the sealing member (1). The join between the teeth (22) and the sleeve (18) is thus broken when the plug (2) is unscrewed. <IMAGE> |
