Connecting element for a threaded joint of self-drilling injection anchors

摘要

The invention relates to a connecting element, in particular a coupling sleeve (1), for a threaded joint of self-drilling injection anchors (2) or allocated parts, with an internal thread (8) formed on a cylindrical base surface (cylindrical area a), the injection anchor (2) or the allocated part having a corresponding external thread (9) formed on a cylindrical base surface, and, to achieve cost-effective producibility and an increased utility value, proposes that a conically tapering base surface (b) adjoin the cylindrical base surface (area a) of the internal thread (8), on which base surface (b) the internal thread (8) continues.
