Patent ID: 8887946

Claim:
An assembly device comprising: an external element comprising a tubular part extending along a first axis; an open-loop ring being elastically deformable between an open position characterized by a first inner diameter of the ring and a closed position characterized by a second inner diameter of the ring, the second diameter being less than the first diameter; wherein the external element comprises an assembly part assemblable with the ring by elastic interlocking, the assembly part comprising at least one of recessed elements or projecting elements arranged on an internal wall of the tubular part; wherein the ring comprises a first assembly part assemblable with the external element by an elastic interlocking, the first assembly part comprising first elements positioned on an external wall of the ring, said first elements having a shape complementing the elements positioned on the internal wall of the tubular part, said shape being complementary when the ring is in the open position; and wherein the ring comprises a second assembly part assemblable with the external element by an elastic interlocking, the second assembly part comprising second elements positioned on the external wall of the ring, said second elements having a shape complementing the elements positioned on the internal wall of the tubular part, said shape being complementary when the ring is in the closed position.
