In a variant, the applicator comprises: a panel and at least one first pair of first and second grippers pivotally connected to the panel with each gripper having loop on an end. The loop is connected to an arm and the arm pivotally attached to the panel. The first and second grippers are configured to rotate in opposite directions to form an open position and come to a stopping point. The loops of the grippers are configured to slide under one another while rotating into a retracted configuration. Two end units are disposed on opposite ends of the panel, configured for being grasped by two independent graspers for fixing the applicator in position.
