Abstract: A socket end closure arrangement comprises a socket 4 in an article 5 and a closure 1 for the socket end. The closure 1 comprises a plug 2 for fitting into the socket 4, and to which plug 2 is attached, preferably tangentially, a disc-like flange 3. The plug 2 has spherically-arranged surfaces having a curvature substantially derived from the surface of a sphere and permitting selection of the orientation of the plug in fitting of the plug 2, preferably in interference-fit manner, into the socket 4 from a plurality of alternative orientations about at least one axis transverse to the longitudinal axis y of the socket 4. The flange 3 preferably locates into a surface recess 7 to become flush with the surface of the article 5. The plug may be physically structured in providing resilience and accordingly may be segmented 24. The axis y may be non-perpendicular to the plane of, or tangent to, the article surface, and the axis x of the recess 7 may not be aligned with axis y.
