Structural assembly and method of assembly thereof

An assembly, comprising:

• a first cardboard assembly member;
• a second cardboard assembly member;
• and
• a connection arrangement that connects together the first and second cardboard assembly members, the connection arrangement including a set of first connector elements and a set of second connector elements;
• each of the first connector elements (i) having a first segment fixedly received within the first assembly member, (ii) having a second segment that projects from the first assembly member and received within the second assembly member, the second segment extending along a first longitudinal axis parallel to two parallel faces of the second assembly member;
• each of the second connector elements (i) extends along a second longitudinal axis normal to said first longitudinal axis;
• and (ii) being fully received within said second assembly member;
• the second segment of each of the first connector elements in said set of first connector elements comprising at least two recesses extending along said second longitudinal axis, at least two first connector elements of the set of first connector elements being disposed parallel to one another, with their corresponding recesses being aligned, such that a second connector element out of said set of second connector elements is received within at least two aligned recesses to thereby interlock the first and second connector elements.
