ABSTRACT:
The open end of a cylindrical housing which may be an evacuable housing, for example a tube for storing blood samples, is closed by means of a cap having an annular wall surrounding the open end of the housing and a seal extending into the cap and the housing. For secure sealing of the housing, the cap is connected by means of a coupling device either to the seal or to the housing or both of these.
