A pile connecting device comprises two plate-shaped members which are adapted for connection with the ends of two pile sections to be joined together and which in the connecting position snugly engage one another by means of planar surfaces. These planar surfaces are provided with registering grooves which extend inwardly from the edges of the plate members and are of dove-tailed cross section, the grooves accommodating locking wedges of double dove-tail configuration in cross section. At their inner ends the wedges have projections which shall cooperate with curved recesses at the inner ends of the grooves. As a result, the wedges when driven into the grooves will be reliably anchored to the plate-shaped members.
