Abstract

　L'invention concerne un élément de joint (10) inséré dans une structure d'assemblage (41), qui est inséré à travers une ouverture d'un élément de mise en prise (20) inséré dans une structure d'assemblage (42), et l'élément de joint (10) est pressé contre l'élément de mise en prise (20) jusqu'à ce que les surfaces plates des structures d'assemblage (41, 42) se réunissent. Une partie de crochet élastiquement déformable formée dans la surface interne de l'élément de mise en prise (20) et une partie de mise en prise d'élément de joint formée dans la surface externe de l'élément de joint (10) sont ainsi amenées en prise l'une avec l'autre et la partie de crochet se déforme élastiquement et se déploie, l'élément de joint (10) et l'élément de mise en prise (20) pouvant ainsi être couplés en douceur l'un à l'autre en un contact. Pour cette raison, une opération nécessitant une force importante n'est pas nécessaire pour une opération d'assemblage, et l'assemblage peut être exécuté facilement sans utiliser d'ustensile d'assemblage tel qu'un tournevis, même au sein d'un ménage.
