ABSTRACT A telescoping tool includes a plurality of telescoping tubes interconnected by coupling means each of which comprises an exteriorly threaded sleeve secured to one end of an outer telescoping tube and having an inner outwardly tapered surface a part of which is of the configuration of a truncated cone, a tubular wedge having an outer surface of compIementary configuration to said part of the inner surface of said sleeve together with an outwardly projecting coupling element preferably in the form of an exterior flange together with a cap sleeve having internal threads and which is threadedly related with the exterior surface of the sleeve and arranged when tightened to force the tubular wedge into the sleeve and toward the adjacent end of the outer tube so as to grip frictionally the exterior surface of an inner tele- scoping tube and thereby to secure the telescoping tubes together in frictional relationship, an inner recess or groove being formed interiorly of the cap sleeve and adjacent its cap portion for receiving the outwardly pro- jecting coupling element of the capered tube so that loosening of the cap sleeve removes the tubular wedge from its position of high friction contact between the inner surface of the sleeve and the outer surface of the inner telescoping tube. If more than two telescopically related tubes are employed to form the tool, additional coupling means may be employed so that the length of the pole may be adjusted to any desired length from a minimum length equal to the length of the outermost sleeve to a maximum length equivalent to the sum of the lengths of all of the tubes or to any pole length between minimum and maximum.
