The bore (30) of the collar (28) has a diameter slightly less than that of the external surface (21) of the attachment cap (16). Friction opposes movement between (28) and (16), its force acting longitudinally (10) on (28). During assembly, the claws (22) deform resiliently, passing over the external bead (36) without displacement between (28) and (16).

During assembly, the claws (22) deform resiliently, passing over the external bead (36) without displacement between (28) and (16). Once (16) butts against the bottle neck, (28) slides along (16) until it covers and surrounds (22). |
