An idler end for a roller tube of a roller blind. The idler end includes a housing having a bore therethrough, an internal partition and a generally cylindrical passageway extending through said partition. The passageway has an internal first should for engagement with a fastener. The idler end includes a shaft having (i) a pin portion for engagement with the roller blind, (ii) a receiver configured to pass through the passageway and for engagement with said fastener, and (iii) a second shoulder between the pin portion and the receiver end, and a biasing member configured to longitudinally bias said pin portion away from said housing.
