A retainer ring holds parts of a socket assembly against relative movement. The retainer ring is disposed in an outwardly facing groove in a first socket part and an inwardly facing groove in a second socket part. A resilient seal ring is compressed between surfaces on the socket parts to press side surfaces of the grooves against surface areas on opposite sides of the retainer ring. When the socket parts are to be assembled, the retainer ring is telescopically positioned on the end of the first socket part. The second socket part is pressed against the retainer ring to move the retainer ring toward the outwardly facing groove along a flaring surface which expands the retainer ring. The retainer ring is pushed into an outwardly facing groove in the first socket part by the second socket part. When the retainer ring is in the groove in the first socket part, the retainer ring cooperates with the grooves in the two socket parts to hold them in their telescopic relationship. As the retainer ring is pushed toward the groove in the first socket part, the seal ring is compressed between the two socket parts to apply preload forces against the retainer ring when the socket parts are interconnected.
