<p>The connector has inclined surfaces (3) and vertically extending recesses (4) which interrupt the inclined surfaces at equal intervals. A dovetail-shaped groove (2) is extended at both ends to the edge area of board surface or plate (1). A dovetail key (20) is offset so that inclined surfaces in the narrow region (30) are interrupted by vertical recesses (40). The dovetail key perpendicular to board surface or plate is inserted laterally in the board surface and is displaced and fixed, so that narrow regions abut on the inclined surfaces of groove in partially form-locking manner.</p> |
