ABSTRACT:
An improved device for interconnecting a pair of different parts together, such as the fastening of a pitot tube to the side wall of an air flow duct of an air conditioning system. The device includes a barrel having a number of resilient legs mounted thereon near one end thereof, the barrel being externally threaded to receive a hex nut or the like. The legs, which initially project laterally from the barrel, are movable into positions extending longitudinally of and adjacent to the barrel as the barrel and legs are inserted into a hole in a second part. The legs spring back after passing through the hole and the outer ends of the legs engage the surface portion surrounding the hole when the nut is tightened on the barrel so that the first part carried by the barrel is effectively rigidly connected to the second part having the hole.
