The body has a centrally disposed securing portion for receipt of a threaded fastener and is of a substantially dished shape presenting sharp peripheral edges for aggressively engaging the interior wall of a tube to resist retrograde movement of the connector axially of said tube. The legs extend generally axially from said body adjacent the periphery thereof and have sharp longitudinal edges for aggressively engaging the interior wall of a tube to resist rotating movement within said tube upon rotating association of a threaded fastener with the centrally disposed securing portion.

Abstract: The invention concerns an anchoring device, more particularly a screw anchoring device, for insertion in an opening, e.g. in the end of a tube, to there form an anchor for a screw or bolt introduced into the opening. The device comprises an internally threaded locking body, preferably a conventional hexagonal nut, and a sleeve which is shaped, at least at one end thereof, to provide a tip portion, e.g. by being cut off obliquely. The device is inserted into the opening with the screw engaging the locking body and loosely accommodating the sleeve, whose tip portion is facing the body. In tightening the screw the locking body becomes wedged between the tip portion of the sleeve and an opposing portion of the wall of the opening. The union body-sleeve will then form a solidly fixed anchor for the screw, which itself can be loosened and tightened as desired.
