Abstract
A nut type plastic fastener has a vertical penetrating space and a plurality of holding pieces facing one another with the space. The facing surfaces of the holding pieces are provided with ridges for engagement with threads of a stud. The lower portions of the holding pieces are connected by means of small-thickness flexible pieces to the lower portion of the fastener body defining the space. When a stud is passed through a gap defined between the holding pieces, the holding pieces are separated from one another as a result of the flexing of the flexible pieces.
