Patent ID: 6938388

Claim:
A straight connector ( 1 ) adapted to be partially inserted, approximately half-way, into hollow profiles ( 2 ) that are connected together end-to-end, said hollow profiles being used to form a spacer frame or spacer for insulated glass panes, the straight connector ( 1 ) defining a cross-section adapted to fit into an inner hollow section of the hollow profile ( 2 ), the straight connector ( 1 ) comprising: a centered recess ( 4 ) on a back of the connector, adapted to face an outer crosspiece ( 3 ) of the hollow profile ( 2 ) in an installed position, into which ends of the outer crosspiece ( 3 ) of the hollow profile ( 2 ) that face each other can be deformed inwardly, wherein the recess ( 4 ) extends across an entire width at the back of the straight connector ( 1 ) and is adapted to be open toward the outer crosspiece ( 3 ) of the hollow profile ( 2 ) in its installed position, the recess ( 4 ) being narrow and having borders which include steep sides ( 9 ) of pieces ( 10 ) that lead up to the recess or steep walls ( 8 ) or perpendicular leading edges ( 11 ) of an opening ( 12 ); parallel side walls ( 16 ) that extend up to the recess ( 4 ), located on both sides of the recess ( 4 ); and cavities (l 7 ), bordered by the parallel side walls ( 16 ), which continue on into the recess ( 4 ) and form a continuous channel at the back of the straight connector ( 1 ) that is adapted to be closed in the installed position by the hollow profile ( 2 ), the cavities and the recess having a greater depth than a depth which corresponds to an inward extension of the deformed crosspieces ( 3 ) at the ends of the hollow profiles ( 2 ).
