A connector for truss work members to a support structure for a mounting interface of a trusswork. The connector has a body with a first portion and a second portion. A central opening is provided in the body having an inner wall configured for receiving a connection end of a truss member. The first portion and the second portion are arranged concentrically. The first portion has first circumferential edge sections, and the second portion has second circumferential edge sections. The first and second circumferential edge sections are spaced apart by gap sections that are configured to receive connecting flanges of a support structure. The gap sections are forming segments along a virtual surface that is curved at least in one direction.
