ABSTRACT:
A pair of identical strap elements are provided, each of which comprises a first substantially planar rectangularly shaped end portion which is notched along its opposite edges to receive the inwardly turned edges of a channel member to which the pipe is to be clamped, a concave mid-section conforming with the curvature of the pipe and a planar opposite end portion which is initially formed with rectangular corners, but one of which corners is punched and bent inwardly at a right angle to the plane of the planar end portion to form a tab. The configuration of the punched-out tab is such as to provide a hooked end with the hook directed downwardly toward the concavity of the mid-section and an arcuate ramp leading to the cut-back in the end which forms the hook. In addition the outermost edge of the planar opposite end portion is notched inwardly toward the midsection to receive the hooked end of another strap element when two such elements are disposed oppositely for face-to-face engagement with each other and with their concave midsections abutting an arcuate area of the pipe. In such complimenting disposition of the two strap elements, when each hooked tab is brought into the notched edge of the other strap element and the opposing planar opposite end portions are squeezed together, the pipe becomes effectively clamped to the channel member.
