Patent ID: 8240107

Claim:
A spacer frame arrangement for insulating associated glass units, the spacer frame arrangement comprising: a spacer profile body extending in a first direction and having a predetermined cross section in a plane perpendicular to the first direction, the predetermined cross section defining a hollow inner space of the spacer profile body with predetermined dimensions in the plane perpendicular to the first direction, the spacer profile body being formed at least on the inside limiting the inner space of polypropylene; and, a connector comprising a connector section having a barbed teeth design with resilient protrusions in a form of teeth formed at one or more outer surfaces of the connector and being adapted to be inserted in the first direction into the hollow inner space of the spacer profile body by having a cross sectional shape perpendicular to the first direction which corresponds, within predetermined tolerances, to the cross section of the spacer profile body limiting the hollow inner space, at least the outer surface of the connector section facing the inner surface of the hollow inner space of the spacer profile body after insertion of the same being made of polyamide, wherein the connector section is inserted into the hollow inner space of the spacer profile body and the inner surface of the spacer profile body is fuse-connected with the teeth.
