Patent ID: 6863465

Claim:
An assembly comprising: a first and a second part to be fixed together, a fixing assembly comprising: a first and a second fixing member intended to engage in each other in a direction of engagement between an engagement position and an assembled position, said first member being linked to the first part and said members being constituted: one by a substantially cylindrical peg, substantially of circular cross section, provided with at least one groove extending substantially in said direction of engagement between a first end and a second end, said groove having a first helical ramp extending in a first direction between said first end and a first intermediate end, and the other by a tubular ring maintaining a passage intended to receive the peg, said ring comprising at least one pin protruding inside said passage, said pin being intended to be inserted into said groove to slide therein, means for guiding in rotation the second member relative to the second part, said means for guiding in rotation the second member relative to the second part preventing axial motion along the direction of engagement of the second member relative to the second part, resilient means linked on the one hand to the second member and on the other hand to the second part, wherein: said groove comprises a second helical ramp extending in a second direction which is opposed to the first direction, between a second intermediate end and the second end, in the assembled position, the pin is disposed in the groove between the second intermediate end and the second end, and the first and second parts are pressed against each other by the action of the resilient means.
