A pivotal connection between a handle and a housing including a pivot defining member biased outwardly into frictional contact with concentric openings in a handle and housing. The member includes a sleeve portion with an outer diameter O s substantially equal to or less than the diameter of the housing and handle openings, the sleeve portion further including a tubular opening having a selected inner diameter I s. The member further includes a longitudinally extending pin portioncircumscribed by a reference cylinder having a diameter D c and an end section inscribing a reference cylinder having a diameter D I, where D I ~ I s < D c < O s, Circumferentially disposed connecting segments project radially outwardly from the pin portion end section and are breakably secured to the sleeve portion. The sleeve portion and pin portion are initially longitudinally secured end to end at circumferentially spaced locations, with the pivot defining member being assembled with the handle and housing by locating its sleeve portion within the housing and handle openings and then breaking the connecting segments by forcing the pin portion into the sleeve portion tubular opening.

Cette invention concerne un pivot de manette de loquet dont le corps élastique est en contact de frottement avec les parois de trous concentriques ménagés dans la manette et le loquet. Le pivot comprend une partie manchon dont le diamètre extérieur Os est pratiquement égal ou inférieur au diamètre des trous ménagés dans la manette et le loquet, ladite partie manchon comportant une ouverture tubulaire de diamètre intérieur Is prédéterminé. Le pivot comprend en outre une tige située dans le prolongement de la partie manchon et s'inscrivant dans un cylindre de référence de diamètre Dc et un embout dans lequel s'inscrit un cylindre de référence DI où DI ~ Is < Dc < Os. Des éléments d'attache frangibles disposés sur le pourtour de la tige et faisant saillie radialement vers l'extérieur rendent celle-ci solidaire de la partie manchon du pivot. Les deux parties du pivot forment à l'origine un ensemble unitaire, réunies bout à bout en différents points espacés sur leur pourtour. Une fois la partie manchon insérée dans les trous ménagés dans la manette et le loquet, on brise les éléments d'attache ci-dessus en forçant la partie tige dans l'ouverture tubulaire du manchon.
