Abstract
The double connector for connecting two bodies, especially for connecting two slabs of stone, marble or the like, consists of two anchoring elements (4,5), one in each body being connected, and a sleeve-like connecting piece (1) including two stud parts on opposite ends. The connecting piece (1) is connectable with the stud parts on the anchoring elements located in drilled holes provided in the bodies. So that the double connector, in addition to having a simple assembly, can absorb comparatively large tensile and compressive forces, at least one anchoring element (4,5) consists of an expansion element (7) received in one (13) of the drilled holes and a anchor core (6) consisting of a cone (8) and a bolt part (6') extending from the cone (8) and provided with a bolt collar (9) spaced from the cone (8). The bolt collar (9) of the bolt part (6') engages or locks in a suitable undercut (15) provided in one of the stud parts. The expansion element (7) is braced in the drilled hole (13) when the anchor core (6) connected with the stud part with the undercut is inserted onto it due to engagement of the expansion element (7) with the end face (E) of the stud part so as to secure the double connector in the drilled hole (13).
