Patent ID: 7735875

Claim:
A pipe coupling device that secures a first pipe to a second pipe, comprising: a collar having a central axis and including a fastening mechanism disposed through a cylindrical body of the collar and transverse to the central axis; and a cylindrical collet, concentrically disposed within the collar and substantially aligned with the central axis, comprising: a first collet portion configured as an upper major arc having a transverse surface angularly offset from the central axis; and a second collet portion configured as a lower minor arc having a complementary transverse surface angularly offset from the central axis that mates with the transverse surface of the first collet portion within the collar, wherein when the fastening mechanism is tightened, the first collet portion is urged to slidably translate in an angular direction along its transverse surface, and flush over the complementary transverse surface of the second collet portion until the first and second collet portions securely clamp the pipes.
