ABSTRACT:
A subsea well assembly has a tubular inner housing that locates within a tubular outer housing. A locking element carried by the inner member is biased outward for engaging a groove provided in the bore of the outer member. The inner member has a metal compression shoulder that has a skirt portion that engages the rim of the outer member. A recess located in the load ring provides slight resiliency to the skirt portion of the load ring. This resiliency allows the load ring to deflect elastically during bending forces exerted on the inner member. The slight deflection of the skirt portion of the load ring results in the locking element moving deeper into the groove to preload the connection.
