Abstract: A push-in tube connector port for connecting a tube to a pressurized fluid system is provided. The push-in port includes a central recess for receiving the tube, a sealing arrangement inside of the recess, a locking ring engaged within the recess, and a tube gripping ring having an inwardly directed gripping edge. The locking ring has a U-shaped cross-section. A number of circumferentially distributed slots subdivides an outer ring wall of the locking ring into a number of outer ring wall portions configured to be elastically deflected towards the center by the flange of an insertion end opening, when the annular double ring component is pressed into the recess, and to elastically flex back outwardly once the outer ring wall portions have passed the flange such that an upper edge of each of the outer ring wall portions engages an inner surface of the flange to secure the locking ring in the recess.

Abstract: A hose connector assembly for connecting a hose to a port of a pressurized fluid system, the system including a socket and an adapter tube in fluid communication, with an end portion of the socket adapted to be connected to a port and having a receiving opening. The adapter tube has a plug-in end portion to be pushed into the receiving opening which is adapted to cooperate with the plug-in end portion to form a plug-in connection mechanism. The adapter tube has a hose connector end fitting adapted to be received in, hold and retain a hose end portion. Complementary locking surfaces of the receiving opening and plug-in end portion are engaged when the plug-in end portion is connected by the plug-in connection mechanism to the socket to lock the adapter tube with respect to the socket against rotation about the longitudinal axis of the adapter tube within the socket.
