Abstract
A telescoping assembly especially suited for vacuum cleaner wands includes a first tube having an outer diameter and a second tube having an inner diameter which is larger than the outer diameter of the first tube. In this way, the first tube fits within the second tube in an axially sliding manner. A collet is positioned within the second tube and encircles the first tube. The collet includes a locking element for selectively securing the first tube in relation to the second tube, the locking element cooperating with a portion of the second tube upon a rotation of the collet to prevent a telescoping movement of the first tube in relation to the second tube.
