ABSTRACT:
A built-in connector element is constructed for being anchored in sandwich ype compound panels. For this purpose the connector element has a central threading for cooperation with further connector components and a body with corners forming anchoring fins for holding the connector element in the compound panel. The cornered body is arranged substantially concentrically relative to said threading and has a rounded flange merging into the anchoring fins. The anchoring fins are so dimensioned that the circle enclosing the outer corners of the fins has a diameter which is equal or larger than the diameter of the flange. In one embodiment the central threading is provided directly in the cornered body. In the other embodiment a threaded member is laterally displaceable in the hollow cornered body, whereby the initial insertion of a screw is made easier.
