Abstract
Devices and systems for tool-less assembly of cable chains that are capable of being retractably stored. The device comprises a first contact element, a second contact element, and a lengthwise member. The first contact element is adapted for movable contact with a receiving member of a first cable chain segment. The second contact element is adapted for movable contact with a receiving member of a second cable chain segment. The lengthwise member is fixedly attached to the contact elements. When an angle between the first and the second cable chain segments is a first value, the lengthwise member experiences elastic deformation, generating a spring force at each contact element sufficient to pull the receiving member of the first cable chain segment rotatably towards the receiving member of the second cable chain segment, thereby reducing the angle between the first and the second cable chain segments to a second value.
