  • Patent number: 4040546
    Abstract: A hanger has an elongated hanger body which includes a pair of shell-shaped hanger halves which are separated from one another along a longitudinal plane of symmetry of the hanger body. Male and female connecting elements in form of pins and sleeves for receiving the pins extend across the plane of symmetry and engage one another when the two hanger halves are assembled. The marginal portions of the hanger halves are formed with grooves and bulges, the bulges being received with snap action into the grooves of the associated one of the hanger halves when the two hanger halves are assembled with one another. The hanger halves are formed with partial bearings which together form a full bearing for receiving a support portion of a shaft of a suspension element of hook-shaped configuration, which bearing is adjacent to and communicates with an opening which leads to the exterior of the assembled hanger body.
