Female fastening element (1, 40, 60, 81) which is designed to be pushed onto a male fastening element which is provided with an external screw thread, the female fastening element having an axial bore (16, 43) for accommodating the male fastening element, and a plurality of segments (30-35, 50-55) which are disposed around the axial bore and each has one or more internal screw-thread parts which together form the internal screw thread of the female fastening element, the segments being movable between a radially outer position, in which the male fastening element can be inserted into the female fastening element without a screwing movement of the female fastening element with respect to the male fastening element, and a radially inner position, in which the screw-thread parts are in engagement with the external screw thread of the male fastening element. The female fastening element comprises a shell body (12, 40, 60) which has been produced from a sheet metal material and has a shell wall which lies around the axial bore, each segment (30-35, 50-55, 62-72) being integral with the metal shell body and being delimited by a substantially U-shaped incision in the shell wall of the shell body and, via a foot, adjoining the shell wall and being bent towards the centre of the axial bore about a bend line which lies in the region of the foot.
