Abstract
A modular retaining device provides ease of assembly and disassembly as well as versatility. Conversion from spring loaded plunger type retention to through hole pin type retention by pressing the retaining module in or out of a through hole cavity provides this versatility without the weakening effect of the intersecting bore hole required for known spring loaded plunger retention systems. A variety of configurations for the retaining element is provided.
