A blanking plug is used for sealing provisionally connection openings (3) of non-installed liquid-operated units, in particular of oil-hydraulic systems (1) for motor vehicles. A section (12) of the blanking plug (10) is inserted into, and fills up, the connection opening (3). The section (12) is provided with a hollow space communicating with a closed portion of the connection opening (3). The hollow space is filled with a material tending to absorb the respective liquid, for example a tampon (17).
