A cap is composed of a cylindrical skirt provided with a central opening, and ensures the locking of a plug in the opening of a neck of a container. A tear-off lid is sealed onto this cap and, by means of a projecting part on a gripping ring of the cap, is connected by a strip to a portion of the upper end of the skirt delimited circumferentially by tear-off lines parallel to the generatrices of the skirt, extending over the entire height of the latter and associated with partial cuts. The skirt tears off when the lid is torn off by means of the ring. The cap is particularly useful for sealing of containers for sterile non-injectable pharmaceutical products.
