A locking top for blocking a stopper in the neck of a vessel comprises an outer body and a cage that is configured to fit into and lock axially in the outer body. The cage comprises an upper ring, a plurality n of branches connected to the upper ring, n/2 median bridges and n/2 lower bridges arranged in alternation on the periphery of the cage, each connecting together two adjacent branches. When the top is in an intermediate holding position in which the stopper is partially pushed into the neck, the lower bridges surround, at least in part, a collar of the neck; the median bridges located, in an axial direction, between the upper ring and the lower bridges are designed to form an open space between them and the collar. 1. A locking top for blocking a stopper in a neck of a vessel , comprising:an outer body; and an upper ring,', 'a plurality n of branches connected to the upper ring and defining therewith a cylindrical general form of the cage,', 'n/2 median bridges and n/2 lower bridges, each connecting together two adjacent branches, the median bridges and the lower bridges being arranged in alternation on the periphery of the cage, each median bridge supporting a first flexible tab intended to block the stopper within the cage, against the upper ring, when the top is in the intermediate holding position, and each lower bridge supporting a second flexible tab,', 'wherein, the top is able to adopt two positions on the vessel: an intermediate holding position in which the stopper is partially pushed into the neck; and a locking position in which the stopper is pushed into and locked in the neck; and', only the lower bridges and the branches surround a collar of the neck of the vessel, and', 'the median bridges are located, in an axial direction, between the upper ring and the lower bridges, such that each median bridge forms an open space between the median bridge and the collar., 'wherein, while the top is in the intermediate holding position], 'a cage configured ...
