A knock-in anchor (110) with an anchor bolt (112) with a truncatedly conically widening 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. By striking the end of the anchor sleeve (116) outside the drilling, the anchor arms (136) are driven over the strutting head (122) and pivoted outwards, thus anchoring them in the securing drilling. The forward end regions (140) of the anchor arms (136) in the fitting direction, 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. |
