ABSTRACT:
Fixing devices for connecting components, particularly prefabricated concrete members and tubbing stones, consist of pluglike anchors adapted to be forced with elastic deformation into anchor holes, which are formed in the components and are open to the joint between the components. As a result, the anchors are frictionally held in and/or positively locked in the anchor holes. The anchors are substantially stiff and have a peripheral surface which at least in portions intended for a retaining engagement with the inside surface of the anchor hole is designed to be elastically deformable at least in an approximately radial direction. The surface consists at least in these portions of a plastic material which has entropy elasticity.
