A vacuum-cleaner pipe has an inner tube telescopingly received in an enlarged end of an outer tube. A retaining element diametrically opposite a slider which can be operated by the user can be received in an annular space between the tubes and on opposite sides of a guide body around which, in at least a partial turn, extends a bar spring which is braced against the guide body and not only provides the bias to the retaining element in the direction in which it presses a detent into a selected recess of a detent strip of the inner tube, but also forms the coupling between the slider and the retaining element so that, upon movement of the slider in one direction, the retaining element is moved in the opposite direction.

Un tuyau d'aspirateur a un tube intérieur reçu télescopiquement dans le bout élargi d'un tube extérieur. Un élément de retenue diamétralement à l'opposé d'un coulisseau qui peut être actionné par l'utilisateur peut être reçu dans un espace annulaire entre les tubes et sur les côtés opposés d'un corps guide autour duquel s'étend, au moins en un tour partiel, un ressort sur barre qui est fixé contre le corps guide et qui non seulement pousse l'élément de retenue dans le sens dans lequel il presse une détente dans un creux choisi d'une bande de détente du tube intérieur, mais aussi forme le raccord entre le coulisseau et l'élément de retenue de sorte que, si le coulisseau se déplace dans un sens, l'élément de retenue est déplacé dans le sens opposé.
