A coupling assembly for a first tubular member, comprising: a receiving member defining an opening adapted to receive the first tubular member, and having an inner portion defining an inner bore dimensioned to receive an end portion of the first tubular member, and an outer portion defining a first internal annular cavity communicating with the inner bore and having a diameter greater than the diameter of the inner bore; an annular locking member having an outer rim portion fitted within the first internal annular cavity, and having an inner portion of generally frustoconical shape angled inboard from its outer rim portion such that its inner rim extends in its relaxed position into the inner bore so that the inner rim contacts and penetrates the outer surface of the first tubular member when the first tubular member is inserted into the inner bore, to inhibit separation of the first tubular member from the receiving member; a stop member abutting the outboard side of the outer rim portion of the locking member and adapted to prevent the locking member from longitudinal outboard movement along the internal annular cavity; and a deformable annular sealing member within the receiving member inboard of the locking member, and extending in a relaxed position into the inner bore to contact the first tubular member when the first tubular member is inserted into the inner bore, to inhibit fluid leakage from the first tubular member toward the annular locking member.
