As described herein, a coupling member for building units includes a ram member which is movably mounted within one of the building units and which has an end adapted for placement within the open end portion of the other building unit. The ram member is provided with a surface in the form of two sloping planes arranged at right angles to each other and obliquely positioned in the longitudinal direction of the ram member. Also provided is a screw member which is adapted to abut either of the sloping planes of the ram member to thereby effectively lock the ram member in either of two positions. The other end of the screw member is adapted to project into a hole arranged in the building unit. |
