Claim:
1. A tube fitting set comprising: two multi-way tube members, each of said multi-way tube members including three tube-connecting segments in fluid communication with each other and each having a distal end formed with an end opening, said distal end of at least one of said tube-connecting segments of each of said multi-way tube members having two locking portions and at least one overflow notch; two couplers each mounted removably to and in fluid communication with one of said tube-connecting segments of a corresponding one of said multi-way tube members having said locking portions and including a cap section covering said distal end of said one of said tube-connecting segments, two spaced-apart resilient retaining portions extending from said cap section and permitting said locking portions to be snapped respectively thereto so as to position said cap section relative to said one of said tube-connecting segments, a guide tube section that extends from said cap section into said one of said tube-connecting segments to guide said cap section to be sleeved on said distal end of said one of said tube-connecting segments and that is adapted to connect with one of the tubes extending into said one of said tube-connecting segments to retain said one of the tubes thereon, a connecting tube section extending from said cap section in a direction away from said guide tube section and adapted for connection with the other of said couplers, and a connecting hole formed through said cap section and in spatial communication with said guide tube section and said connecting tube section,; and at least one clamp disposed between and clamping removably said multi-way tube members, wherein said clamp has two C-shaped clamping portions and a bridging portion connected between said C-shaped clamping portions, wherein at least one of said tube-connecting segments of each of said multi-way tube members has an outer surface formed with an axially extending anti-rotation projection, each of said C-shaped clamping portions having an abutment surface abutting against said outer surface of a corresponding one of said tube-connecting segments, said abutment surface being formed with an engaging groove that engages said anti-rotation projection of a corresponding one of said multi-way tube members for preventing rotation of a corresponding one of said C-shaped clamp portions relative to said corresponding one of said tube-connecting segments.
