A system and method for connecting two flexible containers is provided, in particular for the environmentally sealed connecting of two open ends of tubular films. The method has at least the following method steps of: everting a first open end of a first flexible container over a first ring; everting a second open end of a second flexible container over a second ring, subsequently inserting the first ring through the second ring into the inside of the second flexible container; subsequently aligning, in a parallel and coaxial relationship, the rings in relation to one another; and abutting the rings with the ends clamped in between them.
