Abstract: A connector assembly for sterile connection of two internally sterile containers or tubings comprises two connectors (3, 4). The first connector (3) has a male part (5) inside a housing (6), a connecting device to connect the first connector to a first container or tubing (1), a first deformable barrier (7) spaced from the male part (5) and a chamber (8) between the male part (5) and the first barrier (7). The second connector (4) comprises a female part (9), a connecting device to connect the second connector to a second container or tubing (2) and a second deformable barrier (11) closing the female part (9). In connecting the connectors (3, 4) first both deformable barriers (7, 11) are brought into contact with each other after which the male part (5) of the first connector (3) is put through the second barrier (11) closing the female part (9) of the second connector (4).
