Abstract A saddle member has an axial through bore and is adapted to be applied to a portion of the periphery of a pipe to be drilled. The saddle member is provided on opposite ends with abutments. A clamping band is adapted to embrace another portion of the periphery of said pipe and has two end portions, each of which has a central longitudinal recess and two side strips on opposite sides of said recess. Bearing members bear on said abutments on the side of the saddle member remote from said clamping band. Bolts extend through said bearing members and said abutments and having each a head, which is disposed on the side of said bearing member remote from said abutment and engageable to rotate said bolt, and a screw-threaded shank disposed on the side of said saddle member facing said clamping band. Tightening nuts are threaded on said shanks and comprise each two diametrically opposite, laterally protruding pins, each of which is formed with a slot. Each of said side strips is wound on one of said pins and extends into the slot thereof.
A pipe drill clip, which comprises a saddle member having an axial through bore and adapted to be applied to a portion of the periphery of a pipe to be drilled, said saddle member being provided on opposite ends with abutments, a clamping band adapted to embrace another portion of the periphery of said pipe and having two end portions, each of which has a central longitudinal recess and two side strips on opposite sides of said recess, bearing members bearing on said abutments on the side of said saddle member remote from said clamping band, bolts extending through said bearing members and said abutments and having each a head, which is disposed on the side of said bearing member remote from said abutment and engageable to rotate said bolt, and a screw-threaded shank disposed on the side of said saddle member facing said clamping band, and tightening nuts threaded on said shanks and comprising each two diametrically opposite, laterally protruding pins, each of which is formed with a slot, each of said side strips being wound on one of said pins and extending into the slot thereof.
