<p>The disclosure relates to a tube coupling comprising a coupling body (12) having a throughway (13) open at one end of the body to receive a tube. A collet (25) is located in the throughway having an annular element and radially resilient fingers extending axially from the element toward said open end of the throughway. The coupling body has a stop face (24c) directed along the throughway axis away from said open end and the distal end of the finger has on its inner side a projection (29) to engage a feature on the tube and on its outer side a first, axially facing abutment (30) directed towards the open end of the throughway to engage with the stop face on the coupling body and a further, radially facing abutment (31) engageable with the coupling body. A cover (100) is mounted don the coupling body (12) and has integral radial projections (101) extending through apertures on the cover to engage and act on the cam or face (102) on the annular element of the collet to disengage the fingers of the collet from the end steps 24C to allow release of a tube from the coupling body. <IMAGE></p> |
