Abstract: The present invention is a suspension device comprising a frame and a means for holding a microphone. The means for holding a microphone is secured to the frame by two arms lying in a plane and the arms are shaped to allow movement of the means for holding a microphone in a direction transverse to the plane.

Abstract: The present invention relates to a locking means (1) for use in releasably locking a first tubular structure (100) of a first diameter and a second tubular structure (101) of a second diameter in a predetermined position telescopically in relation to each other. The second diameter is less than the first diameter and the locking means comprises a component (2) adapted for gripping at least the second tubular structure and a component (5) adapted in use to cause the locking means to have a locked position in which the second tubular structure is held in place relative to the first tubular structure and an open position in which the second tubular structure is telescopically movable relative to the first tubular structure.
