A two piece crimping bead is provided. The crimping bead has a crimp bead and a crimping plunger. The crimp bead has a through bore with a first opening, a second opening, and a sidewall. The through bore is adapted to have beading cable passed therethrough. The crimping bead also has a crimping bore intersecting the through bore. The crimping plunger is disposed therein in interference fit with the crimping bore. When the crimping plunger is urged into the crimping bore, the crimping plunger retains the beading cable against the sidewall of the through bore.
