The present invention refers to a connecting rod/piston arrangement for alternative compressor, comprising using at least an intermediate element capable of associating said connecting rod with the piston, wherein both do not radially contact with one another. A process for assembling said connecting rod/piston arrangement for alternative compressor is also disclosed. The connecting rod/piston arrangement for alternative compressor comprises at least a piston (1), at least an intermediate element (2) and at least a connecting rod (3), wherein said piston (1) comprises at least a non-through axial channel (1 1); said intermediate element (2) comprises at least a through axial channel (21 ); and said connecting rod (3) comprises at least a connection end (31). In this regard, the intermediate element (2) is securely housed inside the non-through axial channel (11) of piston (1); and said connection end (31) of connecting rod (3) is securely housed inside the through axial channel (21) of intermediate element (2).
