The system comprises a collar (10) and a washer (28), the collar having a band (12) suitable for co-operating with bearing surfaces (16, 18) of the interconnected tubes (1, 2) via its inside periphery defining a setback (14), and means for tightening the band. The washer (28) is secured to the collar by fastening means (33, 34) and the system further comprises first pre-fitting means (38) for acting when the collar is in the non-tightened state to secure said collar to the first tube when the bearing surface (16) of said first tube is engaged in the setback (14). The clamping system further comprises second pre-fitting means (40) for acting, when the collar (10) is secured to the first tube (1) by the first pre-fitting means (38), to secure said collar to the second tube (2) when the bearing surface (18) of said second tube (2) is also engaged in the setback (14). |
