Abstract
The invention is concerned with structures and with means for joining tubes together to form such structures. A connecting means has a pair of component parts each of which has spigot portions extending oppositely from a boss, the portions being such that a complete connecting means has oppositely extending spigots for insertion into respective tubes. Each component has in its boss a locking means for interaction with corresponding means on another component with which it is assembled to provide resistance to withdrawal of the spigots from the tubes.
