## Abstract

A male pin attaches on lateral edges of shelves and respective female housings on lateral walls of display stands after gluing the shelves and lateral walls. The male pin and its coupling end have hinged rear flaps securable to each other by coupling pegs and recesses, and with coupling lugs and cradles. The female housing has a front track that incorporates a rear clip. The male pin and female housing are secured, respectively, in indentations near ends of front shelf edges and in indentations in lateral walls. For assembly, the pegs/recesses and lug/cradle of the male pin insert in the indentation, for securing by quick engagement at both ends of the front edge of the shelf and laterally exposing the coupling end. The female housing inserts by its rear clip in the lateral wall indentation, positioning the front track thereof to receive the coupling end of the male pin.
