Abstract
A first portion or section of a flexible wrist cord is connected to a second portion or section of the cord by a sliding coupling device including a pair of mating identical housing sections which are assembled to form a housing having an internal cavity. A hook-like clip portion projects from each housing section on one side of the cavity and snap fits into a corresponding aperture within the other housing section to form a positive attachment of the housing sections. The housing sections also cooperate to define openings for receiving the cord sections, and the cavity provides space for receiving opposite knotted end portions of the cord or a crimped fastener which connects opposite end portions of the cord. The cavity also provides for extending the cord sections directly through the housing in parallel spaced relation or for crossing the cord sections when it is desired to increase the sliding friction of the coupling device along the cord sections.
