Abstract
A clamping system to connect a first and a second tube whose facing ends have protruding clamping surfaces is provided. The system comprises a collar comprising a belt able to be clamped around the clamping surfaces. The belt has a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries an outer retaining clip comprising a retaining segment located on the side of the first flank and a first and a second link return linking respectively the retaining segment to a first and a second retaining member located on the side of the second flank. The collar is retained axially between the retaining segment and the first and second retaining members. The retaining segment is able to be elastically deformed to allow the insertion of the end of the tube and to retain it pre-mounted in the collar.
