Abstract
The invention relates to an expansible anchor ( ) for fastening to a panel-shaped building material, having an anchor sleeve ( ) with forwardly projecting expansion tongues ( ) that can be spread open by drawing in an expander body ( ) having an expander cone ( ). The invention proposes to form the expansible anchor ( ) with a locking connection ( ) which locks the expander body ( ) on the expansible anchor ( ) in a position in which the expander body ( ) is drawn in between the expansion tongues ( ) and holds the expansion tongues ( ) in a spread-open position. The invention has the advantage that the expander body ( ) remains in its position in which it is drawn in between the expansion tongues ( ) and holds the expansion tongues in a spread-open position even when an expander screw is unscrewed from the expansible anchor ( ).
