ABSTRACT:
This invention relates to the slide connectors with locking means which are used to removably connect two boards in L-connection and/or three boards in T-connection and/or four boards in a cross connection. The slide connectors with locking means comprises an elongated member with four side surfaces having a retaining slide groove disposed in each of said four sides and a retaining slide rail matching to said retaining slide groove disposed on each end of the board to be connected into L or T or cross connections. One or both ends of said elongated member includes a threaded or a plain hole with a finite depth disposed at the center of the cross section of said elongated member, the cross section of which hole slightly extends into the root of said four retaining slide grooves; whereby, the crest of said retaining slide rail extends slightly into said hole. A set screw or a pin having an indented side surface driven into said hole grabs the root of said retaining slide rail and consequently, establishes a non-slidable connection.
