A joint is created by means of basic fishplates (5), mounted from sides on rails (1, 2), bonded with the rails (1, 2) and filling with its basic body a cavity between the head (K), the stem (S) and the foot (F). An external side of the fishplates (5) fits with external vertical side of the rails (1, 2) head (K) and from its upper part the longitudinal rib (5') enters into the side; said rib (5') bears with its lower part against the foot (F) and passes up to the external side of the foot (F). The longitudinal rib (5') is thicker as the foot (F) in the equal sectional plane. On the external sides of the basic fishplates (5) at least one additional fishplate is placed, which, by its lower part, bears agains the longitudinal rib (5') of the basic fishplate (5) and is bolted together with the basic fishplate (5) because of increasing rigidity of the joint.
