Term for the small wire mesh (filling bracket, wire basket, shipping bracket, French Muselet), with the sparkling wines how champagne or sparkling wine the cork is wrapped and fixed to the bottle neck. This is to prevent the relatively large Carbonic acid pressure in the bottle the cork is catapulted out of the bottle neck. A metal capsule (helmet, plaque) on the head of the natural cork prevents the wire mesh from being cut in (capsule is not necessary for plastic corks).
The clasps are attached mechanically in combination with the corking. Collecting these coveted items is considered Placomusophilie designated. at Perlwein however, an agraffe is not permitted so that it can be distinguished externally and not be confused with a quality sparkling wine. Bottle nets have another purpose; see in this regard under Alambrado (Spanish for wire mesh). See also under MAESTRO (Special cap for sparkling wine bottles), closures and Weingenuss,
