Claim:
A quick-fit connection for pipes comprising: a body comprising at least one spigot, which extends around a longitudinal axis to a free end, suitable for being at least partially inserted in a pipe, the spigot forming first and second axially spaced annual seats defined on an external surface of the spigot, the first annular seat being furthest way from the free end of the spigot; first and second fluidic sealing elements received in the corresponding first and second seats; a blocking element removably couplable to the body, suitable for working on an outside of the pipe and for cooperating with the body, so as to keep the spigot engaged in the pipe; wherein said blocking element comprises at least one annular blocking body, which defines a passage section for the pipe and which comprises blocking teeth extending radially internally so as to interfere with the pipe; wherein the blocking element defines a viewing window through the thickness of the blocking element; and wherein: when the blocking element is joined to the body at a first end of the blocking element, the spigot projects axially beyond the blocking element, and the viewing window of the blocking element is radially aligned with the first annular seat.
