MASONRY PLUG

摘要

A masonry metal-plug for anchoring fixtures to a masonry wall comprises a plurality of expandable sectors (2) held mutually associated by a single tulip type spring and effective to be expanded by inserting an expander cone (19) under the pull applied by a bolt (17) threaded therein. On respective expandable sectors (2) projecting teeth (6) are formed effective to engage with seats (7) formed in an adjacent sector (2) in such a way as to hold the expandable sectors correctly beside one another and prevent the plug from rotating within the hole whereinto it is inserted.
