Abstract: 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.
