Abstract
In a snap connection system in which a shaft is inserted into a tube to a predetermined position, where co-operating surfaces on tube and shaft engage as in a laterally acting wedge. Two axially spaced spring loaded balls on one side of the tube urge the shaft into wedging engagement with the tube when in the pre-determined position. During insertion, a further spring loaded ball on the opposite side of the tube adjacent the wedge apex urges the shaft out of wedging engagement with the tube. A detent in the shaft accommodates this further ball at the predetermined position, locating the shaft axially and permitting wedging. The balls are biased by a spring sleeve and a tang thereon locates the sleeve on the tube. The tang may extend to the tube interior to coact with a detent in the shaft so that unclipping is necessary for disassembly. Alternatively, a spring loaded pin extending through sleeve and tube wall may accomplish the same end.
