Abstract
A safety device for Roman shades includes multiple loop members connected to the shade and multiple restriction members are connected to multiple loop members. Each restriction member includes two extensions which spirally wrap to each other so as to define an opening therebetween. Multiple engaging members are connected to the lowest loop members and each engaging member has two claws between which a through hole is defined. Each claw includes a slit defined axially in a distal end thereof. Multiple control ropes each have a top end connected to the top box and the lower end of each control rope extends through the openings of the restriction members and is connected to an insertion member which is inserted into the silts and engaged with the through hole of the engaging member corresponding thereto. When the control ropes are pulled laterally, the insertion members are disengaged from the engaging members.
