Linear connector of plastic material for joining hollow spacing profiles A, B and hollow bar profiles of a multiple insulating glass, comprising a flat, longitudinal body which is to be inserted with its one end into the spacing profile A and with its othe r end into the spacing profile B, the surfaces of which are provided with an abutment eleme nt posi- tioned in the center of the linear connector, which abutment element touches the front faces C and D of the spacing profiles on insertion of the linear connector into the spac- ing profiles which are to be connected to one another, wherein the mentioned longitudi- nal body comprises a double-T-cross-section the distantly parallel and horizontal cross- bars of which being connected by at least one vertical center bar and contacted at least partly in the mounted condition of the linear connector by the opposing surfaces of the inner wall of the spacing profiles. In order to improve the sealing effect of the linear connector as well a its seat within the hollow spaces of the metallic spacing profiles which are to be connected to one another and to avoid that the gap between the spacing profile bodies arises after mounting the linear connector it is proposed that that at least one of the two cross-bars of the double- T-cross-section is provided inthe center of its length with a recess making visible the surfaces of the spacing profiles in their mounted condition within the area of their ends comprising the front faces of the spacing profiles positioned opposite to on e another so that welding of these ends by heat treatment is possible without melting the plastic ma- terial of the linear connector. |
