Abstract: A table section aligning and fastening device comprises a unitary plastic male member including a projecting nose portion and a complementary unitary plastic female member defining an alignment channel for receiving the nose portion of the male member. The members mount to the underside of respective table sections to be joined at their respective abutting edges. The nose portion is both laterally and vertically tapered so as to cooperate with the alignment channel defining portion of the female member in guiding the table sections into lateral and vertical alignment as they are pushed together. The female member includes an integral resilient finger which resiliently engages in a retaining notch formed in the nose portion to hold the members and the table sections together.
