a first pipe and a second pipe extending one another,
a sleeve having a first end into which is fitted one end of the first pipe and a second end into which is fitted one end of the second pipe,
for each pipe, a clamping collar arranged around the sleeve and clamping the sleeve against said pipe,
for each pipe, an anchoring element secured to said pipe and comprising a first fastening means,
for each clamping collar, a retaining element secured to said clamping collar and having a through-passage, and
for a pair of first fastening means and a pair of retaining elements, a tie passing through the through-passages of the two retaining elements and having, at each end, a second fastening means cooperating with one of the first fastening means of the pair of first fastening means in order to fasten each end of the tie to an anchoring element.

### Claim 2 (depends on 1)
