A joint coupling is disclosed for connecting sections of conduit. The present joint coupling includes a male connector portion having an inner side and an outer side, having a barb on one or both of the sides. A gasket is received on the male connector portion, and has one or more fins on the side opposite the barb. A female connector portion receives and engages the male connector portion and includes a first side having a lock down lip for engaging the barb and a second side for contacting the gasket fins. The fins bias the connector portions in an interference to create a transverse locking force that securely retains the connector portions. The connector portions can be formed directly on the sections of conduit, or can be formed on a discrete conduit cap or an intermediate coupler, for joining sections of conduit.
