Two parallel head rails and a passage are provided on the fixing face to be passed through by the cord and performing a fixing job.
An object of the present invention is to provide a fixing device in a venetian blind, which is arranged to have a better strength and durability.
Referring to FIGS. 1 through 4, basically, a fixing device in a venetian blind in accordance with the present invention is an integral piece made of high molecular material and comprises a cord engaging part 1, a core 2, and a band passing part 3. The cord engaging part 1 and the band passing part 3 are oppositely disposed to each other with respect to the core 2. The cord engaging part 1 is for fixing a bracing cord and the band passing part 3 is for fixing a positioning band.
