Abstract

A clamping system for connecting a first tube and a second tube, the clamping system including a collar which includes a belt able to be clamped around clamping surfaces of the first and second tubes, 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 at least one retaining loop disposed outside the belt. The loop has a first end fastened to the collar and a second end which is free and which is located on the outer side of the first flank. The loop is able to adopt a position of active retaining configuration in which its second end protrudes towards the axis of the collar relative to the edge of the first flank, and to be deformed relative to this active configuration so that the second end is moved radially outwardly.
