The system permits two tubular parts ( 1, 2 ) to be assembled, the assembly being able to be locked or released, without a cumbersome device being required. It includes in particular a toothed crown ( 10, 20 ) on each of the two tubular parts ( 1, 2 ), each with a series of teeth ( 11, 21 ) disposing of straight radial shoulders ( 12 ) on the first toothed crown and angled shoulders ( 22 ) on the second toothed crown. This assembly is completed by a locking ring ( 30 ) disposing of teeth ( 31 ) designed to fit between the shoulders ( 12, 22 ) of the two crowns, once they have interlocked. Turning the locking ring ( 30 ) allows, using the angled locking faces ( 33 ) of the teeth ( 31 ), the two tubular parts ( 1, 2 ) to be locked together. A locating ring ( 40 ) may be used to center the parts and receive the shear loads due to a transversal mechanical change. The system may be applied for large tubular part assemblies that need to be dismantled. |
