The invention relates to a coupling between two objects by means of a coupling element. Each object comprises a panel with a continuous hole with four inward protruding tongues which are disposed at 90~ to each other and extend over angles of about 22.5~. The coupling element comprises a shank, an insert stop member on both sides so that the coupling element can be inserted in the one or the other direction into the hole, four locking cams on each end zone of the shank which each extend over angles of 22.5~ disposed at 0~, (90~ - 22.5~), 180~, (270~ - 22.5~), and rotation stop members. The coupling element can be inserted into the hole in a chosen orientation as desired in one of four equidistant angular positions and then rotated through about 22.5~ in the one or the other direction, wherein rotation locking means fix the chosen angular position, so that the coupling element cannot be removed from the hole b axial dis lacement alone.

La présente invention concerne un assemblage entre deux objets effectué au moyen d~un élément d~assemblage. Chaque objet comprend un panneau avec un trou continu et quatre languettes faisant saillie vers l~intérieur, disposées selon un angle de 90° les unes par rapport aux autres et s~étendant sur des angles d~environ 22,5°. L~élément d~assemblage comprend une tige, un élément d~arrêt d~insertion sur les deux côtés de telle sorte que l~élément d~assemblage peut être inséré dans l~une ou l~autre direction dans le trou, quatre cames de blocage sur chaque région d~extrémité de la tige s~étendant chacune sur des angles de 22,5°, disposés à 0°, (90° - 22,5°), 180°, (270° - 22,5°) ainsi que des éléments d~arrêt de rotation. L~élément d~assemblage peut être inséré dans le trou selon l~orientation souhaitée dans une des quatre positions angulaires équidistantes, puis entraîné en rotation sur environ 22,5° dans l~une ou l~autre direction, les moyens de blocage de rotation fixant la position angulaire choisie de telle sorte que l~élément d~assemblage ne peut pas être retiré du trou par simple déplacement axial.
