Abstract

Des nervures inclinées (30, 32) dépassent des parois latérales opposées (20, 22) d'une pièce de retenue (14) d'un dispositif de retenue (10), et par rapport à la direction dans laquelle l'élément (12) étant retenu est inséré par une ouverture (16), la nervure inclinée (30) et la nervure inclinée (32) sont inclinées du même angle dans la direction longitudinale de l'élément (12) étant retenu. Par conséquent, lorsque l'élément (12) étant retenu est inséré dans la pièce de retenue (14) par l'ouverture (16), une force dans la direction de cisaillement et une force dans la direction perpendiculaire (compression) par rapport aux nervures inclinées (30, 32) sont produites par la force d'insertion.
