In a handlebar comprising an elongate handle arm and a boss which supports the central part of the arm, the boss has an aperture with a generally channel-shaped region for receiving the central part of the arm, and a pressure body is mounted in the aperture for selective movement into a thrust position against the central part of the arm to press the central part into the generally channel-shaped region of the aperture so as to clamp the arm relative to the boss.
