Abstract: The assembly comprises a first nestable component (12, 32), a second nestable component (14, 22), and a first swiveling component (20). The first nestable component comprises a housing formed in a nesting surface (121, 321) adapted to place opposite to a complementary nesting surface (14E, 22E) of the second component. The housing forms a reservoir for a solid mass of hot-melt adhesive, and is hidden when the first and second components are nested one inside the other. The first and second nestable components are made of a material that is resistant to a temperature. The assembly comprises a first nestable component (12, 32), a second nestable component (14, 22), and a first swiveling component (20). The first nestable component comprises a housing formed in a nesting surface (121, 321) adapted to place opposite to a complementary nesting surface (14E, 22E) of the second component. The housing forms a reservoir for a solid mass of hot-melt adhesive, and is hidden when the first and second components are nested one inside the other. The first and second nestable components are made of a material that is resistant to a temperature equal to or greater than the melting temperature of the adhesive. The material of one of first and second nestable components is heat conductor to allow the melting of the adhesive by heat conduction through this heat conducting components. The material of the heat conductive components comprises metal, carbon or ceramic. The reservoir has an annular groove. The first swiveling component comprises a connected end (20A) intended to be attached by a fastening screw on a support component, and a swiveling end intended to contact with a complementary swiveling end of a second swiveling component complementary to the first swiveling component, where the support components is first or second nestable components. The connected end of the first swiveling component and the support component comprise a through seat for bearing a head of the fastening screw, and a threaded hole for screwing the screw. The support component comprises a threaded hole for screwing the screw, and a through seat for bearing a head of the fastening screw. The through seat is masked, when complementary swiveling components are assembled together. The second swiveling component is provided with a passage of a tool to access that tool to the head of the fastening screw. The tool passage is masked by a masking component. The second swiveling component and the masking component form the nestable components. The threaded hole is opening to allow optionally the contact of a free end of the fastening screw with the second or the first nestable components and with the complementary swiveling end of the second swiveling component. A washer having axial elastic effect is interposed between the head of the fastening screw and the through seat. A clearance between the nesting surfaces is 0.5-2 10 -> ->1 millimeters. Independent claims are included for: (1) a method of assembling a set of elements; and (2) a method for disassembling the assembly.
