A connector includes one or more spirals securing a fluid conduit to the connector for fluid communication with another hollow object such as another fluid conduit. The spiral(s) press/compress and seal the conduit around an outer circumference of an end of rigid, hollow insert of the connector. Another portion of the connector may include spiral(s) that press/compress and seal a second conduit around a second end of the insert, or may include a hose-coupler that connects to a second conduit. Thus, two fluid conduits may be fluid-sealed to an inner-passageway of the insert, by tightened spiral(s) or by tightened spiral(s) and coupler combination, so the conduits are in fluid communication with each other. The spiral(s) may be retained in, and released from, the tightened condition, by a ratchet-based latching and unlatching system.
