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.
