Abstract: The configuration, structure and materials of the components of a control device as well as a control device assembly are disclosed. The control device includes an elongated strip portion which is bent into a J-shaped configuration so that an opening in the J forms a receiving slot for receiving and securely holding a tubular member which encloses a portion of a cable. The receiving slot is slightly smaller in width than the diameter of the tubular member and the slot is bendably expandable while the tubular member is compressible. When the tubular member is in the slot the biasing forces (inward from the control member and outward from the tube) hold the tube in place and allow the tube and cable to be easily and conveniently placed in the control device. The tubular member may include a flange at one end which faces toward the main part of the cable. The other end of the tubular member abuts an expanded abutment on a cable which forms the cable end.
