TELESCOPIC TUBE COMPRISING A SCREWLESS, QUICKLY SLIDING ADJUSTING DEVICE HAVING A BLOCKING MECHANISM

摘要

A telescopic tube having an adjusting device comprising an inner toothing angularly interrupted by a longitudinal recess and a male element having an outer toothing angularly interrupted by a second recess so as to axially slide along the longitudinal recess in a first predetermined angular position and selectively engage with the inner toothing in a second predetermined angular position different from the first predetermined angular position for rigidly connecting the bushing to the male element in axial direction.
