ABSTRACT:
A connector or connecting together elongated frame bars having T-shaped grooves on side surfaces is a single elongated structure having a longitudinally uniform cross-sectional shape. The connector has a central wall and is symmetric with respect to the plane of this central wall. Pairs of wings protrude from the central wall to be inserted into the grooves in the frame bars to be connected. The wings of one of the pairs protrude perpendicularly to the central wall. The wings of the other pair are cross-sectionally Z-shaped so as to be able to elastically engage in and with the grooves of the frame bars. Each wing has a mutually outwardly protruding part with a slope for being pressed against edges of the grooves such that the connector can be correctly positioned.
