Patent ID: 7543804

Claim:
A gas spring adapted for use with an associated gas line, said gas spring comprising: a spring wall at least partially defining a spring chamber; and, a connector fitting secured on said spring wall and operative to form a substantially fluid-tight seal with the associated gas line; said spring wall including: a first wall portion at least partially defining a passage extending therethrough, said passage having an axis, and said connector fitting being received within said passage and sealingly engaging said first wall portion; a second wall portion spaced radially outwardly from said first wall portion and at least partially forming a first axially-extending groove therebetween; and, a third wall portion connected between said first and second wall portions and at least partially forming a closed end of said first axially-extending groove, said third wall portion being substantially more capable of flexing than said first and second wall portions thereby permitting displacement of said first wall portion relative to said second wall portion and thereby reducing stresses in said first wall portion that are capable of separating said first wall portion from said connector fitting.
