Tube connection comprises insert with widened part having annular groove which is securely fitted inside tube in machined annular re-entrant in tube outer wall

摘要

The connection comprises a tube (1) and an insert (2) which can be securely fitted inside the tube. The insert comprises a widened part (20) having an annular groove (21) and a receptor space (22). The tube has several transverse holes (12) in its median zone or end parts. The tube outer wall is machined in order to form an annular re-entrant corresponding to the annular groove so as to immobilize the insert inside the tube and thus allowing the connection of the tube.
