A blind cord safety device for use in controlling an adjustable blind having a looped control cord and a looped control chain by enclosing the loo ps has housing within which are disposed a rotatable wheel adapted to engage the chain loop thereabout and a U-shaped cord loop receiver adapted to receive the cor d loop in a peripheral groove formed thereon. The receiver is mounted within t he housing so as to permit limited longitudinal but not lateral movement of the receiver within the housing. A spring is disposed within the housing between the receiver and the housing top so as to normally urge the receiver away from t he housing top so as to avoid slack in the cord as a result of the cord stretching over time as a result of use.
