摘要

The invention relates to a method of making a pipe connection and to a pipe connection where an insert end (2) having an outer diameter that is larger than the inner diameter of the pipe (1) is inserted into the pipe (1). A flexible pressure ring (4) is then transferred on the connection, the inner diameter of the ring being normally smaller than the outer diameter of the pipe (1) transferred on the insert end (2). The connection is easy to make and it is also applicable for pipes with a large diameter, and the connection is strong and tight due to the flexible pressure ring.
