摘要

Fastening device (10) for rails (r) of railway tracks, comprising a monoblock, compact and adhering assembly formed by a metal top plate (20), a metal bottom plate (30), and an elastomer material (40) located between both plates (20, 30), such that there is no direct contact between said plates (20, 30), the fixing device (10) being characterized in that the upper plate (20) has a central projection (21), whereas the lower plate (30) has a central cavity (31) delimited by a closed contour (32) and is dimensionally adapted to receive the central projection (21) of the upper plate (20); such that the solidary fit between the upper and lower plates (20, 30) generates a tongue-and-groove connection thereof through the elastomeric material (40) intermediate.
