Abstract

L'invention concerne un ensemble d'éléments, par exemple des tubes, et en particulier des portions de manches d'un aspirateur (3, 5), assemblés entre eux de manière télescopique, dans lequel des positions sélectionnées sont verrouillables au moyen d'un élément d'encliquetage (8) qui, en plus, comporte un bouton d'encliquetage actionné par pression (10), et une saillie d'encliquetage (13) disposée sur le bouton (10), ce bouton étant mis à découvert sur un premier élément télescopique (5), en vue d'être actionné, la saillie d'encliquetage (13) s'engageant dans un deuxième élément télescopique (3). En vue d'obtenir un élément d'encliquetage amélioré, en particulier un élément d'une hauteur minimale avec un nombre minimum de pièces, le bouton d'encliquetage (10) est en saillie, pour permettre son actionnement, sur l'élément télescopique extérieur (5), et coopère, par l'intermédiaire d'un support du type culbuteur, avec l'élément télescopique intérieur (3).
