Abstract: The present invention is directed to a removable coupling watertight joint. The joint consists of a male piece which is inserted within a female piece. Both the male and female pieces may be attached to flexible pipes or to other fluid flow devices. Integrally molded onto the female piece are two flexible clasping tongues which deflect inward to engage the male piece.Also integrally molded onto the female piece are means for biasing a joint coupling bushing in a locked position. The joint coupling bushing surrounds the female piece and has internal projections which cause the elastic clasping tonques to deflect inward and engage the male piece. In its locked position, the joint coupling bushing deflects the flexible clasping tongues inward thereby engaging the male piece.
