ABSTRACT OF THE DISCLOSURE A grommet includes an eyelet and a washer both of rigid plastics which are matable together so as to be set in a fabric or sheet material. The eyelet has a barrel having on one end thereof an annular locking flange projecting radially outwardly and an annular recess 16 adjacent to the locking flange 14. The washer has an annular rib and a plurality of locking tongues projecting radially inwardly from the annular rib. When the eyelet and the washer are coaxially combined within each other with the fabric or sheet material sandwiched there- between, the locking tongues are snapped over the locking flange into the annular recess. The washer is now retained or trapped on the barrel by the locking flange against removal. The advance in the art is in that the grommet can be easily attached to sheet material without the need for any attachment tool. Furthermore, the grommet has parts snappable together so as to be set in sheet material, without being permanently bent or deformed.
