Abstract
A device for shallow anchoring a member to a surface of a receiving material, particularly a receiving material with reinforcement close to the surface, includes a hollow cylindrically shaped anchoring member with a load engagement member connected to it for holding the member to be anchored. The anchoring member is formed of two axially extending cylindrically shaped hollow sleeves (5, 6) fitted one within the other. At least one of the sleeves has axially extending expandable slots. The sleeves are formed of an inner sleeve (5) and an outer sleeve (6) with the inner sleeve (5) having an outer diameter (a) and the outer sleeve having an inner diameter (i) with these diameters increasing towards the leading ends of the sleeves, that is, the ends inserted first into an annular bore in the receiving material.
