ABSTRACT:
A quick connect tube coupling has a connector body with an external threaded portion and a passage extending therethrough. A sheet metal nut and tube retainer member has an opening therethrough with a helical edge engaging the external threaded portion to threadably connect the connector body and this member. The connector body passage is adapted to receive and telescopically pilot a tube end on opposite sides of an O-ring mounted in a groove in this passage. The O-ring is adapted to receive and peripherally seal the tube end. The nut and tube retainer has at least one integral retaining arm extending angularly inwardly toward the tube in the direction of entry thereof into the passage that terminates in a tip normally located in an interference position relative to the bead so as to be contacted and deflected outwardly thereby to permit continued entry of the tube end into the passage and after travel of the bead therepast to resume its interference position on the other side of the bead to retain the tube in the connector body.
