Method for production of a horology assembly, and horology assembly thus obtained

A method for production of a horology assembly of a first component and a second component, one of the first and second components being a spring and the other of the first and second components being a flange, the method comprising:

• supplying the first component comprising at least one element made of elastic material, provided with a tongue, wherein portions of the first component extend along the tongue and past an end of the tongue so that the first component is present on both sides of the tongue and past the end of the tongue;
• supplying the second component provided with at least one cut-out or opening;
• permanently assembling the first and second components,
• wherein the first and second components cooperate so as to create the assembly, wherein the tongue is accommodated in the at least one cut-out or opening so as to form an obstacle between the spring and the flange;
• wherein the assembling of the first and second components comprises:
• performing a mechanical action on the tongue in order to deform the tongue elastically;
• putting the tongue into the at least one cut-out;
• ending the mechanical action on the tongue, and
• further comprising, before the performing of the mechanical action, implementing elastic deformation of the at least one element made of elastic material in a vicinity of the tongue, without deformation of the tongue, in order to make the tongue come out.
