ABSTRACT:
A connector designed to form a butt joint between two channel profiles, or between one such profile and some other member, comprises an elongate wedge piece with flanks diverging downwardly toward the channel bottom and a spring clip with similarly diverging legs having serrated lower edges and straddling the wedge piece over part of its length. A central web of the spring clip, spacedly overlying the top surface of the wedge piece remote from the channel bottom, terminates in a tongue whose tip enters a slit in that surface which it approaches at an acute angle of inclination. A screw with a shank traversing a slot in the web of the spring clip is threaded into the wedge piece and, upon tightening, forces the serrated edges into firm engagement with lateral channel walls while reducing the spacing of the wedge piece from the web with consequent decrease of the angle of inclination of the tongue which therefore exerts a longitudinal thrust upon the wedge piece whose opposite end is anchored to the member to be joined to the channel profile whereby this member is drawn into close contact with the adjacent end of that profile. The anchoring of the wedge piece to the other member may be effected by a second spring clip, symmetrical to the first one, whose tongue extends in the opposite direction.
