Abstract

A quick-connector for terminal fastening of a penetrating rebar (7) to a perpendicularly oriented concrete dowel (2), the connector comprising a wire clip (1) having a deflected segment of wire of the length (L) at least partially made of resilient-elastic metal, wherein the wire clip (1) includes, with respect to a primary turning arc (3), arms (5, 5′) that are mirror-symmetrical to an angle-bisecting plane (4), wherein each arm (5, 5′) forms a deflected secondary turning arc (6, 6′) transverse to the primary turning arc (3) and a clippable hook (8, 8′) that rests force-lockingly into a radial external surface zone (9), of a terminal radial expansion (1), of the concrete dowel (2).
