A threaded sleeve of plastics material, e.g. in the form of a cap, which is suitable for screwing onto a bottle opening with an external thread. The thread of the threaded sleeve is divided into segments. These segments can be separated from one another in the peripheral direction by spaces of at least 0.4 mm and can have a length in the peripheral direction of 3 to 10 mm. Threaded sleeves of this type can be manufactured with simply constructed moulds and demoulded in a simple manner. After the demoulding the thread segments do not mark the external wall of the threaded sleeves.
