A coupling device comprises a body in which a passageway is formed which extends from an end aperture of such body to receive a pipe. A collar is positioned partially within the passageway to allow axial translation and has an annular flange outside the end aperture and flexible arms which extend in the passageway. The coupling device further comprises a safety mechanism having a cylindrical portion capable of being fitted on the portion of pipe straddling the end aperture so as to position the cylindrical portion between the pipe and the collar. The safety mechanism also has a safety fork connected to the cylindrical portion and which accommodates positioning of the collar between the body and the annular flange of the collar to inhibit axial movement of the collar towards the body of the device. |
