ABSTRACT:
An article 10 for insertion into an opening, for example for use as a closure plug in a screw-threaded hole, comprises a body 18 and two projections 22 extending outwardly from the body 18. The outer extent of the projections 22 is circular about the axis of the body 18 except for two gaps 24 which are oppositely disposed. The body 18 is tapered backwards to enable the projections 22 to fold backwards in a compact fashion so that the article can fit large and small diameter openings.
