  • Patent number: 5338071
    Abstract: One end portion of a pipe, which has a circumferentially extending external bead at the one end portion, is insertable into the internal sockets of an array of arms which are axially movably received in one end portion of a sleeve. The arms have external surfaces which cooperate with an internal surface of the sleeve to permit limited axial movements of the arms between first and second positions. When in the first positions, the arms can be flexed radially outwardly to thus permit insertion of the bead into or its extraction from the sockets. The internal surface of the sleeve and/or the external surfaces of the arms can but need not be conical, either entirely or in part. The sleeve can be inserted into a bore or hole of a nipple on a radiator or carburetor in a motor vehicle. One or more O-rings or other suitable sealing elements are installed between the sleeve and the external surface of the one end portion of the properly installed pipe.
