    • Disclosed is a protection device for a blind string. The protection device includes a bellows tube provided in a tubular structure, allowing the blind string to pass through an inner part thereof, and having a length increased or reduced in a longitudinal direction of the blind string, a first module coupled with a lower end portion of the bellows tube and having an inner part to which an end portion of the blind string is locked, and a second module decoupled from the first module at an upper portion of the first module while the bellows tube is interposed between the first module and the second module, such that the bellows tube is folded. The bellows tube has a difference in the thickness of the skin thereof such that the bellows tube is automatically spread due to elasticity thereof when the second module is moved up from the first module.
