A cord fastener includes an insert having a lateral inner cord hole and provided at a lower portion thereof with elastic provisional retaining claws opening outward and catches for securing the provisional retaining claws; a shell having an insertion hole for insertion of the insert, outer cord holes communicating with the insertion hole and alignable with the inner cord hole, provisional retainers provided on the inner surface of the insertion hole below the outer cord holes for engaging with the tips of the provisional retaining claws in a first state when the inner and outer cord holes are approximately aligned, and pushers provided on the inner surface of the insertion hole below the provisional retainers for pressing the provisional retaining claws inward in a second state when the insert is pressed more deeply into the insertion hole than in the first state, thereby causing the provisional retaining claws to engage with the catches so as to prevent them from colliding with the provisional retainers; and a coil spring provided in the insertion hole for biasing the insert in the direction of projecting it from the insertion hole. |
