摘要：A knock-in anchor (110) with an anchor bolt (112) with a truncatedly conicallywidening strutting head (122) on the forward end to be introduced into the

corresponding securing drilling. On the anchor bolt (112) can slide an anchor sleeve (116)which has a plurality of anchor arms (136) formed by slitting over a part of its length. Bystriking the end of the anchor sleeve (116) outside the drilling, the anchor arms (136) aredriven over the strutting head (122) and pivoted outwards, thus anchoring them in thesecuring drilling. The forward end regions (140) of the anchor arms (136) in the fittingdirection, which are limited against the rest of the anchor sleeve (116) by a

circumferential groove (138), together have the outer shape of two truncated cones(140a, 140b) bearing against each other's smaller-diameter faces.
