Abstract
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 with each other with the fabric or sheet material sandwiched therebetween, 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.
