Abstract
The invention relates to a secure lock for a lift cord of a window blind or shade, which includes a head rail, a bottom rail and a shading unit combined between the head rail and the bottom rail. The shading unit has plural connecting members respectively engaging with an annular secure lock, except the connecting member positioned closest to the bottom rail engaging with a cap-shaped secure lock instead. A lift cord is strung in the annular secure locks, with the end fastened with the cap-shaped secure lock. An opening is formed in a ring of the annular secure locks and a groove formed in a curved portion of the cap-shaped secure lock. Thus, the lift cord can be released if an object is accidentally trapped between the lift cord and the shading unit, achieving a secure effect.
