Claim:
A method of manufacturing a cap for a neck of a container, wherein an elongate tubular skirt, able to surround the neck and equipped both with means of returning it around the neck and with an external operating tab extending over just a peripheral portion of the skirt and allowing the cap to be opened, is molded, wherein, at least at one longitudinal level of the skirt, the wall of the skirt is molded circumferentially around the skirt in such a way that the radial dimension of its peripheral portion associated with the tab is smaller than the radial dimension of the remainder of the skirt, and wherein, at said longitudinal level of the skirt, cuts are then made through the wall of the skirt so as to delimit, around the periphery of the skirt, frangible bridges of which at least one is situated in the peripheral portion of the skirt associated with the tab while at least one other of the bridges is situated outside of this portion, which bridges, before the cap is first opened, connect a non-removable skirt part equipped with the retaining means to a removable skirt part equipped with the tab.
