ABSTRACT:
An anchoring plug for anchoring objects to a support structure includes an expansible sleeve, an expander body driven into the expansible sleeve and a screw for driving the expander body into the expansible sleeve. A ring-shaped spring member, which forms a bearing for the expansible sleeve, is positioned at the trailing end of the expansible sleeve. The spring member has the external diameter greater than that of the expansible sleeve and, may due to its properties be compressed to the external diameter of the expansible sleeve.
