ABSTRACT:
A modular assembly is provided for use in frame structures which are assembled by joining frame members to connector or fitting members to allow such structures to be easily and quickly assembled and disassembled without the need for a separate assembly tool. In the assembly the frame member telescopically engages the fitting member and both members are constrained from relative rotational and translational movement by a resilient retainer. The retainer has a general spring-like band configuration which includes a backbone portion having two open extending ends. The retainer is flexed over one of the joined members and its backbone engages at least one half of the perimeter of that member. The installed and tensioned length between the two retainer ends is greater than the length between the same ends in a free state, thereby clamping the structural members together. An alignment pin extends radially inwardly from the retainer backbone and engages both members to lock the retainer in place.
