Abstract
The system includes a collar (10) and a washer (28), the collar having a tightenable 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). The washer (28) is secured to the collar and the system further includes first pre-fitter (38) for acting when the collar is in the non-tightened state to secure the collar to the first tube when the bearing surface (16) of the first tube is engaged in the setback (14). The clamping system further includes second pre-fitter (40) for acting, when the collar (10) is secured to the first tube (1) by the first pre-fitter (38), to secure the collar to the second tube (2) when the bearing surface (18) of the second tube (2) is also engaged in the setback (14).
