Abstract

A bolt fastener includes a plurality of fixing structures that are arranged radially around a receiving space for a bolt and are axially pivotable, wherein the fixing structures have, in the direction of an axial receiving space for a fastening bolt, engagement faces for engagement with a bolt and have, at diametrically opposite ends, bearing faces with which the fixing structures are supported counter to an outward movement, wherein bearing structures for the bearing faces are also provided, which cooperate in a supporting manner with the bearing faces, wherein the bearing face and bearing structure are dimensioned such that they disengage when the fixing structures are pivoted counter to the insertion direction of the bolt, wherein the radial spacing between the bearing structures and a bolt mounted in the receiving space is smaller than the entire extent of the fixing structures.
