  • Patent number: 5074336
    Abstract: A pipe clip of open frame strip material is formed of a front half ring, having a diameter slightly in excess of the outside diameter of an irrigation pipe about which the half ring is fitted. An inverted L-shaped support member includes a horizontal top bar and a vertical right angle rear clamping bar whose ends are respectively fixed to the center of the half ring and to the center of a base horizontal rear cross bar. The horizontal rear cross bar of the base is integral with a pair of horizontal laterally opposed parallel arms whose ends remote from the base rear cross bar are fixed to the ends of the half ring respectively. A cylindrical end plug fitted internally of the open end of an irrigation pipe is maintained in position. Preferably, the irrigation pipe has an integral radially outwardly projecting collar which prevents axial movement of the pipe clip upon engagement of the half ring with the side of the collar remote from the open end of the irrigation pipe.
