Zusammenfassung:	An expansible anchor for anchoring in a drilled hole, having a shank. An expansion sleeve of the expansible anchor can be arranged to be expanded radially by drawing in an expander body. In order to hold the expansion sleeve in place axially during expansion in a drilled hole there is arranged on the shank a resilient ring which has an annular main body having a weakened position, so that to modify its diameter the resilient ring is deformable in the circumferential direction. At least one projection extending radially outwards from the main body is arranged on the resilient ring.
