Abstract
Abstract An electrical connector member including a hollow housing member with an internal restricted passageway, an adjacent outer radial shoulder and a reference surface axially spaced from the shoulder oppositely to the passageway; and an insert member snugly retained against axial movement in first and opposite axial directions by said shoulder and surface, the insert member including a restraining surface in abutment with said shoulder, the restraining surface being shaped by plastic deformation of the weakened peripheral surface portion on the insert member by the wall of the restricted passageway during the final stages of the positioning of the insert member. The insert member before deformation includes the weakened peripheral surface portion formed by a plurality of axially extending knurls, and an adjacent protective collar which protects the weakened portion from deformation until the collar has passed through the restricted passageway and the insert member is in the final stage of positioning.
