    • The present invention regards a barrier plug system (3) for sealing off a pipe (1), comprising a plug body, a first and a second end plate surface (11, 31) arranged on opposite sides of the plug body and at least one circumferential sealing means (6) and means (8) for setting the plug system (3). The plug body comprises at least two separate plug body elements (10, 30) movable relative each other and the at least one sealing means (6) is arranged abutting two opposite annular pressing surfaces (12, 32) formed by the plug body, which are moved towards each other during setting of the plug system (3). The pressing surfaces (12, 32) are limited in the movement against each other by stop means and pre-tensioned to move toward each other by at least one tensioning device (7).
