A cord fastener includes an insert (1) having a first through hole (2h), a shell (11) having an insertion hole (12) into which the insert (1) is fitted and second through holes (13) communicating with the insertion hole (12) and, when the insert (1) has been fitted into the insertion hole (12), communicating with the through hole (2h) for permitting a cord to pass through the first and second through holes (2h, 13), a coil spring (21) for biasing the insert (1) in the direction causing the insert (1) to project from the shell (11), whereby the cord (S) passing through the first and second through holes (2h, 13) is clamped between the insert (1) and the shell (11) owing to the biasing force of the coil spring (21), the wall of the insert (1) defining the first through hole (2h) having a pair of opposed linear ridges (2he) formed on the lower side thereof to extend in the axial direction of the first through hole (2h) and project inward and/or the walls defining the second through holes (13) being formed as inclined surfaces (13f) which taper inward. <IMAGE> |
