A locking tensioner for a roller blind. The roller blind is of the type having a roller and a looped chain or cord to impart rotational movement to the roller. The locking tensioner comprises first and second members, each having a first end and a second end. The first ends have apertures dimensioned to receive therethrough the chain or cord of the roller blind. The first and second members are rotatably secured to one another and rotatable about an axis between a locked and an unlocked configuration. When the first and second members are in their unlocked configuration the apertures are aligned permitting the chain or cord to freely move through both of the apertures. When the members are in their locked configuration the apertures are at least partially misaligned restricting the movement of the chain or cord through the apertures. The locking tensioner includes a spring biasing the first and second members toward their locked configuration. -' - - ---- - ---- ----- - -- -- ---- -- --- -- --------- -- ---- - -- ------
