A plastic eyelet includes a female eyelet having an annular locking jaw on the inner circumference thereof and a male eyelet having an annular protrusion on the outer circumference of a cylindrical column thereof and an uneven surface on a bottom plate thereof so that, once they are combined, they can not be separated or spun freely each other. They can be easily recycled since the material of the sheet is the same one as the eyelet.
