Assembly for tightening and securing male and female parts fitted together

An assembly for tightening and securing 1 a first part and a second part fitted together, the first and second parts having complementary forms, the assembly comprising:

• a support structure, the second part being attached to the support structure;
• at least one contact surface of the first part contactable with the second part;
• and
• at least one annular ring mounted on a periphery of the second part, said annular ring being rotationally mounted and fixed in an axially translational manner to the second part on which the annular ring is mounted when the annular ring abuts with the second part, and arranged to interact with a peripheral surface of the first part during a rotation of the annular ring in relation to the first part, the annular ring being fixed in the axially translational manner between a stop of the second part on which said annular ring is mounted and an edge of the support structure to which the second part is fixed, wherein the support structure is secured to the second part on which the annular ring is mounted by a central rod, which interacts with the second part and supports said second part which is locked in a translational manner against the support structure.

A method for the assembly of a first part with a second part, which have complementary forms, by a tightening and securing assembly, the method comprising:

• positioning the first and second parts relative to one another, the assembly including at least one contact surface of the first part contactable with the second part and at least one annular ring mounted on a periphery of the second part, said annular ring being rotationally mounted and fixed in an axially translational manner to the second part on which the annular ring is mounted, and arranged to interact with a peripheral surface of the first part during a rotation of the annular ring in relation to the first part, the annular ring being fixed in the axially translational manner between a stop of the second part on which said annular ring is mounted and an edge of a support structure to which the second part is fixed;
• contacting the annular ring with the periphery of the first part which is complementary to the second part which supports the annular ring;
• and
• pivoting the annular ring in relation to the periphery of the first part which is complementary to the second part which supports the annular ring.
