Abstract
A method of manufacturing a strut comprising end portions and an intermediate portion, said method comprising the steps of providing a tubular member and forming a connecting portion in the tubular member, characterised in that the tubular member has an average initial first wall thickness (t1) before forming the connecting portion, and the connecting portion is formed by axial compression of a portion of the tubular member until the portion has a second average wall thickness (t2), where t2 > t1; followed by at least partially flattening the thus compressed portion of the tubular member, so as to form a two-layer connecting portion.
