ABSTRACT:
A connector having a main body and a first group of at least four projections which extend outwardly from the body in a common plane. A second group of at least four projections extend outwardly from the body at an angle of between 15.degree. and 75.degree. to the aforesaid plane and preferably at a 45.degree. angle to the said plane. The projections of each group are equi-angularly spaced about an axis normal to the plane and the projections of the second group are angularly staggered by half the angle between adjacent projections of the first group about the axis relative to the projections of the first group. Each projection is of non-circular, and preferably triangular, cross-section and the body and projections are made of non-flexible plastics material. Such connectors are used to connect together elongate members having tubular ends to form a framework structure.
