ABSTRACT:
A fixing element which can be keyed in a hole in a solid base has a tie bolt and a key which is movably mounted on a key surface slanting relative to the central longitudinal axis of the tie bolt. There is furthermore provided a power store which is supported on the one hand against an abutment of the tie bolt, and, on the other hand exerts a pressure force onto the key. Provided also is a ring which holds together the tie bolt and the key. In order to ensure with such a fixing element a simple construction and simple possibilities of assembly for a short distance from the base, the power store applies constantly against the key, the inelastic ring in a position in the region of the key surface of the tie bolt clamps the tie bolt and the key against each other under the pressure force of the power store, and the ring in a position behind the key surface holds the key freely movable in longitudinal direction relative to the tie bolt.
