Plastic grommet

A grommet comprising a female member made of synthetic resin which includes a cylindrical body having a top with a collar that extends outwardly, four slits extending from a lower end of the cylindrical body toward the collar, four elastic stoppers defined by said slits and a catch provided at a lower end of each of said elastic stoppers and facing inwardly, and

• a male member made of synthetic resin which includes a head, a leg extending integrally from the head, four sectioned dents provided in the leg into which each said catch of the elastic stoppers become engaged and an inclined portion that extends from each of said four dents outwardly toward the head to a peripheral surface of the leg,
• the grommet being characterized in that the leg has an enlarged diameter portion located above the inclined portions which is a circle in section and is provided with lateral engagement faces opposing said head and each having an arcuate outer edge formed by a peripheral surface of the enlarged diameter portion and a linear inner edge formed by a flat surface of the larger diameter portion which is parallel to an axial center line of said leg, the engagement faces being circumferentially spaced at regular intervals whereby the catches on the elastic stoppers of the female member are deflected outwardly by the inclined portions of the male member when the male and female members are assembled and are held stopped by said engagement faces.
