Abstract: The invention relates to a leak-tight container comprising a bag (2) formed of a flexible film made of polymer and a leak-tight connection device that is intended to engage with a complementary connection device of a sterile chamber, the connection device comprising a flange (6) to which the bag (2) is bonded, characterized in that the container comprises a two-layer leak-tight reinforcing strip (10) composed of a first layer (11) made of polystyrene and of a second, reinforcing layer (12) made of a material compatible with that of the bag (2) to allow the reinforcing strip (10) to be directly bonded to the bag (2), the rigidity of the second layer being greater than that of the first layer (11), the reinforcing strip (10) being inserted between the flange, which is made of polymer, and the bag such that the first layer (11) is bonded to the flange and the second, reinforcing layer (12) is bonded to the bag.
