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.
A fastening device comprising: an elongated barrel for carrying an elongated part which is to be mounted to a wall with the part extending through a hole in the wall; a number of resilient legs coupled to the barrel adjacent to one end thereof and extending outwardly therefrom, the legs being bendable into positions contiguous to the barrel when the barrel and legs are to be inserted into the hole in said wall; the legs being capable of springing outwardly after the barrel and the legs have been inserted into the hole so that the ends of the legs will be engagable with one side of the wall surrounding the hole, said barrel having a threaded outer surface portion near the opposite end thereof; and a nut threadably engagable with said outer surface portion of the barrel, said nut adapted to be moved along the barrel and into coupled relationship with the opposite side of the wall for securing the barrel to the wall after the barrel and legs have been inserted into the hole.
