The clamping element comprises an elastic clamping arm, a support arm and a connecting arm. The connecting arm forms an opening portion and extends from the support arm to the longitudinal arm. The opening portion of the connecting arm is set around the engagement shoulder portion and engages therewith. A lower end of the support arm forms a coupling end. The coupling end is coupled to the coupling portion. The elastic clamp arm connects to the support arm and extends to the longitudinal arm. A front end of the elastic clamp arm engages the engagement flange. The elastic clamp arm penetrates the opening portion, moving elastically.
  • In view of the above structural design, the terminal structure is advantageously characterized by structural simplicity, ease of molding, low cost, and ease of assembly.
  • One of the coupling portion and the coupling end is a projecting coupling end. The other of the coupling portion and the coupling end is a coupling aperture. The projecting coupling end is inserted into the coupling opening.
  • The longitudinal arm comprises a surface. The surface faces the clamping element. On the surface a wavy strip is formed.
  • The cross arm bends down to form a leg.
