Abstract
A tongue plate stopper has a first disc having its webbing side face formed with at least one needle to be inserted through a webbing; and a second disc having a fitting portion for fitting the needle therein. At least one of the first and second discs has its webbing side face formed with a plurality of pins for biting into the webbing. The needle of the first disc projects from the central portion thereof. The fitting portion of the second disc has a hole. The pins include a first set of pins projecting from the circumferential edge of the back face thereof and at a circumferential spacing from one another, and a second set of pins projecting from the middle portion between the needle and the circumferential edge and at a circumferential spacing from one another. The second disc has its webbing side face formed with a first circumferential groove, which extends in the circumferential direction at a radius substantially equal to that of the first set of pins, and a second circumferential groove which extend in the circumferential direction at a radius substantially equal to that of the second set of pins, so that the first set of pins can have their tips engaging with the first circumferential groove whereas the second set of pins can have their tips engaging with the second circumferential groove.
