L'unité de maintien (12) comprend : un trou d'introduction elliptique (13) qui est formé sur la plaque de base (11) et dans lequel le tuyau en forme de U (23) est introduit ; une nervure de renfort (14) qui est formée d'un seul tenant sur la face avant de la plaque de base (11) et qui est disposée sur au moins un côté dans la direction du grand axe du trou d'introduction (13) ; une griffe (16) qui est disposée en faisant saillie vers le centre à partir du centre gauche et/ou du centre droit du trou d'introduction (13) dans la direction du petit axe du trou d'introduction (13) ; et une paroi circonférentielle qui va d'une extrémité de la nervure de renfort (14) à la griffe (16) le long de la circonférence externe du trou d'introduction (13) et qui comprend un élément qui change la position de la griffe (16) dans la direction du petit axe du trou d'introduction (13) au moyen d'une force externe qui est appliquée par l'intermédiaire de la griffe (16). Le tuyau en forme de U (23) étant maintenu dans l'unité de maintien (12), la griffe (16) s'accroche sur un arc circonférentiel interne (23a) du tuyau en U (23) et est en regard de la face avant de la plaque de base (11) dans la direction d'introduction pour le tuyau en forme de U (23).
