An elastic rail fastening device which uses a metal spike having a projecting jaw, the lower part of the spike being buried in a concrete support. A deformed S-shaped plate spring is provided with one end contacting the upper surface of a spring receiver, a first bent-down portion urged downwardly for depressing the upper surface of the rail flange as laid on the concrete support, a middle portion having the upper surface contacting the projecting jaw, a second bent-down portion for contacting the side of the spring receiver, and the other end contacting the side of the rail flange. The spring receiver is interposed between a guide on the concrete support and the second bent-down portion, whereby the spring receiver pushes up the one end of the spring.
