Abstract of Disclosure Plug means (10, 18) for lockable sealing of a passage opening with a support surface (19) intended for positioning the plug means. Simple lockability and demountability are brought about by virtue of the plug means comprising a sealing plug (15) for interaction with the sides of the passage opening, a retaining means (129), connected to the sealing plug, for interaction with a hook means (20) connected to the passage, and a flexible resilient connecting element (149) between the sealing plug and the retaining means.
