A musical wind instrument has a hollow, generally tubular body made up of a first body section and a second body section which may be telescopically interfitted to define the assembled wind instrument. Alignment and locating structures are located respectively on the first and second body sections for defining a predetermined orientation therebetween when interfitted into assembled condition. The alignment and locating structures include an axially projecting button-like member mounted on a peripheral surface of one of the body sections, and an axially inwardly extending recess in the other of the body sections of complementary form for receiving at least a portion of the projecting member when the first and second body sections are telescopically interfitted and brought into a desired radial alignment and fully axially and telescopically engaged.
