ABSTRACT:
A collet for locking a tube in a tube coupling body is moulded in plastics and comprises an annular collar having a plurality of arms extending from the collar generally parallel to the collar axis. Each arm has a head at its distal end spaced from the collar for engaging between a tube and coupling body to lock the tube in the coupling body. Different materials are used for the heads of the collet and the rest of the collet whereby the heads are stronger and relatively rigid whereas the rest of the collet is relatively flexible.
