Two leaf springs, above and below the knurled adjusting knob, help unlock the jaw when pressure on the handle of the wrench is released. Pipe wrenches are not intended for regular use on hex nuts or other fittings. However, if a hex nut becomes rounded (stripped) so that it cannot be moved by standard wrenches, a pipe wrench can be used to free the bolt or nut, because the pipe wrench is designed to bite into rounded metal surfaces. Pipe wrenches are classified by the length of the handle.

While many simple plumbing tasks can be completed with a few common hand held tools, other more complex jobs require specialised tools, designed specifically to make the job easier. Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, dies, and joining tools such as soldering torches and crimp tools. New tools have been developed to help plumbers fix problems more efficiently. For example, plumbers use video cameras for inspections of hidden leaks or other problems; they also use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench- less sewer line replacement.

Steel pipe (or black iron pipe) was once the most popular choice for supply of water and flammable gases. Steel pipe is still used in many homes and businesses to convey natural gas or propane fuel, and is a popular choice in fire sprinkler systems due to its high heat resistance. In commercial buildings, steel pipe is used to convey heating or cooling water to heat exchangers, air handlers, variable air volume (VAV) devices, or other HVAC equipment. Steel pipe is sometimes joined using threaded connections, where tapered threads (see National Pipe Thread) are cut into the end of the tubing segment, sealant is applied in the form of thread sealing compound or thread seal tape (also known as PTFE or Teflon tape), and it is then threaded into a corresponding threaded fitting using two pipe wrenches.

Each verse is about a new number he has just written, but every time, upon hearing it, his close friends point out to him that this one is not of his usual style, and that he should forget it and start again. The songwriter then figures he can sell his failed composition to this one contemporary singer (a different one at each verse, namely Jean- Patrick Capdevielle, Bernard Lavilliers, and Francis Cabrel), but he never manages to convince them, even though each time the song in question is of the style of the given artist in turn. Persistent, he goes back to writing yet another, better song, and so on to the next song-artist combination until at the end, fed up, he fiercely sets off to write one for his very own self, one with mopeds and motorbikes and leather jackets and pipe wrenches and all, along with cheap word puns. This final verse is where Renaud did not forget to parody himself as well, as he has at other times in his career.
