ABSTRACT:
The disclosure relates to a tube coupling body (13) of circular external cross-section having an internal throughway open at one end to receive a tube with a collet form tube locking device in the open end of the throughway to lock a tube in the coupling body. The coupling body has on its outer side an encircling groove spaced from said one end of the body and a grab ring mounted in the groove of V-shaped cross-section facing the axial direction of the ring towards said one end of the coupling body. One limb of the V-shaped grab ring is lodged in the groove and the other limb projects from the groove at its free end for gripping engagement in a bore in which the coupling body is inserted.
