The snap-lock fitting includes a pair of half portions that are configured to join together around a pipe. The half portions include at least one half-cylinder portion extending from a first end to a second end, where the at least one half-cylinder portion has a first mating surface with a ridge and a second mating surface with a recess, and where the ridge of a first of the pair of half portions is configured to engage a recess of a second of the pair of half portions. Also disclosed is a method of installing the snap-lock fitting. ## Claims ### Claim 1 A snap-lock fitting, comprising: a pair of half portions that are configured to join together around a pipe, where each of the half portions comprises: a flange; at least one half-cylinder portion extending outward from the flange, where the at least one half-cylinder portion has a first mating surface with a ridge and a second mating surface with a recess, and where the ridge of a first of the pair of half portions is configured to engage a recess of a second of the pair of half portions. ### Claim 2 (depends on 1) The snap-lock fitting of claim 1, where the snap-lock fitting defines a bore axis, and the ridge extends along the first mating surface in a direction that is substantially parallel with the bore axis. ### Claim 3 (depends on 2) The snap-lock fitting of claim 2, where the ridge extends along the first mating surface in a direction that is substantially perpendicular to the bore axis. ### Claim 4 (depends on 1) The snap-lock fitting of claim 1, further comprising at least one alignment tab extending from one of either the first mating surface or the second mating surface. ### Claim 5 (depends on 4) The snap-lock fitting of claim 4, further comprising at least one alignment recess disposed in one of either the first mating surface or the second mating surface, where the at least one alignment recess is configured to receive the at least one alignment tab. ### Claim 6 (depends on 1) The snap-lock fitting of claim 1, where the at least one half-cylinder portion comprises at least a first half-cylinder portion and a second half-cylinder portion. ### Claim 7 (depends on 6) The snap-lock fitting of claim 6, where the first half-cylinder portion has a greater diameter than the second half-cylinder portion. ### Claim 8 (depends on 1) The snap-lock fitting of claim 1, where the at least one half-cylinder portion is tapered and decreases in diameter from the flange to an end opposite the flange. ### Claim 9 (depends on 1) The snap-lock fitting of claim 1, further comprising at least one half-annular ridge formed on an interior surface of the at least one half-cylinder portion, where the at least one half-annular ridge is configured to engage the pipe and form a seal with the pipe. ### Claim 10 (depends on 1) The snap-lock fitting of claim 1, where the recess comprises a cross-sectional profile configured to receive and maintain a cross-sectional profile of the ridge. ### Claim 11 (depends on 10) The snap-lock fitting of claim 10, where the cross-sectional profile of the ridge is L-shaped. ### Claim 12 A snap-lock fitting, comprising: a pair of half portions that are configured to join together around a pipe, where each of the half portions comprises: at least one half-cylinder portion extending from a first end to a second end, where the at least one half-cylinder portion has a first mating surface with a ridge and a second mating surface with a recess, and where the ridge of a first of the pair of half portions is configured to engage a recess of a second of the pair of half portions. ### Claim 13 (depends on 12) The snap-lock fitting of claim 12, where the snap-lock fitting defines a bore axis, and the ridge extends along the first mating surface in a direction that is substantially parallel with the bore axis. ### Claim 14 (depends on 12) The snap-lock fitting of claim 12, further comprising at least one alignment tab extending from one of either the first mating surface or the second mating surface. ### Claim 15 (depends on 14) The snap-lock fitting of claim 14, further comprising at least one alignment recess disposed in one of either the first mating surface or the second mating surface, where the at least one alignment recess is configured to receive the at least one alignment tab. ### Claim 16 (depends on 12) The snap-lock fitting of claim 12, where the at least one half-cylinder portion comprises at least a first half-cylinder portion and a second half-cylinder portion. ### Claim 17 (depends on 16) The snap-lock fitting of claim 16, where the first half-cylinder portion has a greater diameter than the second half-cylinder portion. ### Claim 18 (depends on 12) The snap-lock fitting of claim 12, where the at least one half-cylinder portion is tapered and decreases in diameter from the first end to the second end. ### Claim 19 (depends on 12) The snap-lock fitting of claim 12, further comprising at least one half-annular ridge formed on an interior surface of the at least one half-cylinder portion, where the at least one half-annular ridge is configured to engage the pipe and form a seal with the pipe. ### Claim 20 A method comprising: providing a pipe fitting comprising: a pair of half portions that are configured to join together around a pipe, where each of the half portions comprises at least one half-cylinder portion extending from a first end to a second end, where the at least one half-cylinder portion has a first mating surface with a ridge and a second mating surface with a recess, and where the ridge of a first of the pair of half portions is configured to engage a recess of a second of the pair of half portions; and applying a solvent weld to at least one of the pair of half portions; and joining the pair of half portions around a pipe.
