Front seat rear cover thing repair | Citroen C5 X7

In this video, I attempt to repair a small defect on the rear part of the driver&seat. Citroen C5 X7 front seats have some nifty sheathing on the back that protects against kicks and scrapes from rear passenger&feet. However, one of the spots where their held in place is comprised of a fragile little plastic pin that breaks easily. That&what I try to fix here.
