Abstract
A locking clip (1) for air conditioning ducting or the like where the ducting (13, 14) is of the type which has flanges (11, 12) protruding upwardly and generally at right angles from the ends of the ducting. The clip 1 is adapted to clamp the outer faces of the flanges (11, 12) at the same time, resist sliding of the clip (1) along the mated flanges (11, 12) by the action of central tabs (5, 6) protruding from the spine (4) of the clip (1) between the inside, mating faces of the flanges (11, 12). In one form serrations on the ribs (5, 6) help to maintain frictional engagement between the ribs (5, 6) and the inside faces of the flanges (11, 12). The locking clip (1) is particularly suited to use with clip arrangements on air conditioning duct so as to improve the resistance of such clips to creep along the mating flanges (11, 12) under the influence of gravity, vibration and the like.
