A hose coupling wherein a sleeve is made of one piece with axially parallel elastic arms engageable with an external rib of a pipe which is inserted into one end portion of the sleeve. The other end portion of the sleeve is sealingly connected with and surrounds an end of a hose, and the sleeve is surrounded by a turnable or axially movable locking ring having prongs which are caused to bear against the adjacent arms so that the arms are urged against the rib. The sleeve has one or more elastic tongues which can snap behind the adjacent portion or portions of the locking ring to hold the ring in the operative position and to indicate that the ring is maintained in the operative position. The arms have internal grooves for reception of adjacent portions of the rib. The prongs are provided with internal projections which must ride over ramps and hurdles on the respective arms during translatory or angular movement of the locking ring to its operative position, and the arms are further provided with stops which arrest the respective projections when the ring reaches its operative position.
