ABSTRACT:
The disclosure relates to a tube coupling comprising a coupling body having a throughway open at one end of the body to receive a tube. A collet is located in the throughway having an annular element and at least one radially resilient finger extending axially from the element toward said open end of the throughway. The coupling body has a stop face directed along the throughway axis away from said open end and the distal end of the finger has on its inner side a projection to engage a feature on the tube and on its outer side a first, axially facing abutment directed towards the open end of the throughway to engage with the stop face and a further, radially facing abutment engageable with the coupling body when the axially facing abutment engages the stop face to constrain the distal end of the finger against radial outward movement and thereby to prevent release of the projection on the finger from the feature on the tube and release of the tube from the coupling body.
