A self-locking coupling device for coupling to a fitting having a radially outwardly facing groove using a coupling body with a central bore and an axially extending collar having a throughbore including a spring and actuating pin with a locking tab and further having first and second catches corresponding to and engageable with first and second slots in a rotatable locking ring mounted concentrically about the collar so as to position the locking tab within the throughbore in an unlocked position and within the central bore in a locked position so as to restrict the axial movement of the coupling body relative to the fitting when the groove is radially aligned with the pin. |
