Abstract: A water-tight splice connector made from an existing connector, including a first housing and a plurality of pins mounted in means for splicing the pins together located in the housing. A first seal member is located at one end of the housing behind the splicing means and pins. A retainer member engages the housing behind the seal member to protect and secure the seal member in place in the housing. A terminal locking member is insertable in the end of the housing opposite the end receiving seal member to lock and align the pins in place within the housing. A second seal member is located in a second housing containing female terminals for receiving the pins in the first housing. An interfacial seal member is located between the first housing and second housing to seal both housings from outside moisture and water. In the case where the first and second housings are used to connect the wires of two harnesses together, the splicing means is made smaller to permit the wires to bypass the splicing means.
