In a ram locking device for securing the ram of a chipless forming machine, more particularly a heavy press, wherein the tool-carrying ram, movable up and down in the press frame relative to the bed of the press, is supported by the head of an axially adjustable tension rod, the unlocking, more particularly the release of the tension rod, is improved if the tension rod is statically cushioned and is automatically pressure-relieved as the release begins.
