Patent ID: 8555480

Claim:
A coupling for connecting an element of a fluid circuit in fluid communication to a pipe having a pipe end, the coupling comprising: a generally tubular body having an internal body channel therethrough, the body comprising: a first body section extending axially between a first end portion couplable to the element for connecting the element in fluid communication with the body channel, and a second end portion formed by a tubular first wall having a first opening therethrough; and a second body section extending axially between a first end portion couplable to the pipe for connecting the pipe in fluid communication with the body channel, and a second end portion formed by a tubular second wall having a second opening therethrough, one of the second end portion of the first or the second body section being received coaxially in the second end portion of the other body section to define a chamber, with the first and the second opening being aligned in registration, and a clip received in the chamber, the clip having a generally annular locking portion deformable from a normal state to a flattened state, the clip in the flattened state of the locking portion being insertable through the aligned first and second openings into the chamber, and the clip returning in the chamber to the normal state of the locking portion with the locking portion extending transversely in the chamber, whereby with the pipe end being received in the chamber coaxially through the clip, the deformation of the clip locking portion from the normal state to the flattened state is delimited by the pipe so as to prevent the clip from being extracted from the body.
