Abstract
A cord connection device for roll-up shades has a coupling member that fits over a receptive member. The body of the receptive member has a section configured to receive the coupling member in a manner to provide a connection such that when a selected force acts on a cord attached to the coupling member or the receptive member the coupling member will separate from the receptive member. The body of the receptive member can have a second section configured to receive the coupling member in a manner to provide a connection such that the coupling member will not separate from the receptive member or can have a third section configured such that the coupling member will separate when a second selected force acts on the cord or can have all three sections.
