Abstract: A grommet is disclosed, which grommet comprises a female member of a U-shaped end face containing a U groove for accommodating a stretched cord and provided at one extremity of said U groove with an elevated wall rising from the bottom of said groove and at the other extremity with a projecting wall extending inwardly from one side wall and a male member adapted to fit the U groove of the female member for fast engagement therewith, whereby the engagement of the male and female members gives rise to a laterally elongate opening on the side incorporating said elevated wall and a longitudinally elongate opening on the side incorporating the projecting wall. When the male and female members are brought into mutual engagement with a cord interposed therebetween, the cord is fastened in position in its twisted state within the grommet.

Abstract: Disclosed is a grommet made of a synthetic resin, which comprises two members adapted to be coupled into embracing engagement, said members each provided at the opposed end portions thereof with a pair of inclined protrusions of which the directions of inclined edges, when observed in front elevation, cross each other. When said two members of the grommet are coupled with each other, therefore, said inclined protrusions closely approach each other at both said end portions so as to firmly grip a cord passed between the two members and said close mutual approach of the inclined protrusions causes the cord to twist itself between one end portion and the other end portion of the coupled members because of said crossed relationship of the directions of the inclined edges of said protrusions. This twist in the cord serves the purpose of preventing the cord from freely moving in the direction of its length.

Abstract: A one-piece plastic U-nut for retention on the edge of an apertured panel wherein the device is capable of accepting a wide variety of panel thicknesses.
