1. A hydraulic fracturing apparatus, comprising:
a) an assembly that includes a tool body and a work string;
b) wherein the work string is connected to and depends downwardly from the tool body;
c) a flowline that is spaced laterally away from the tool body and work string;
d) a clamp body having a first end and a second end, with said first end spaced away from said second end;
e) a first clamp segment located at said first end of said clamp body, wherein said first clamp segment has a fastening mechanism and a first concave member with a first concave surface;
f) a second clamp segment located at said second end of said clamp body that has a second concave member with a second concave surface;
g) wherein said first clamp segment concave surface is sized and shaped to engage the assembly of said tool body and work string;
h) wherein said second clamp segment concave surface is sized and shaped to engage said flowline;
i) the clamp body having a pair of spaced apart flanges connected by a web, said web having spaced apart end portions, each of said flange and said web connecting respectively at said web end portions to said first and second concave members;
j) each clamp segment having opposed slotted or apertured plates, each flange having a curved edge that connects the flange to a respective clamp segment;
k) a first concave member that is connectable to said first clamp segment in a connected position that connects said first clamp segment and said first concave member to the assembly of the tool body and work string;
l) a second concave member that is connectable to said second clamp segment and that connects said second clamp segment and second concave member to said flow line flowline; and
m) each said concave surface closely conforming to said work string or to said flow line between clamp segment upper and lower edges.
