A safety plug

Abstract

A safety plug (10) for use in a bore hole (12) comprising a bore wall (14). The safety plug comprises a body (22) having a leading end (24) and a trailing end (26), and at least one flared portion (32). An anchoring element (36) extends at least partially around an associated flared portion (32). Axially displacement of anchoring element (36) relative to its associated flared portion (32) causes the anchoring element to bear against the flared portion and transitions the anchoring element between an unexpanded condition and an expanded condition. A nose, comprising conical elements (46), extends longitudinally from the leading end of body (22). The nose is longitudinally compressible.
