Coupling construction.

摘要

A coupling operable between a shaft member (22) and tubular member (19) retains the shaft member at an inserted position within the tubular member. A resilient engaging ring (24) fits onto the tubular member and has a concave portion (24a) projecting radially inwards through a hole defined by the tubular member and into a concavity defined by the shaft member. A sleeve (25) is movable axially from an unlocked position in which the ring is expansible to accommodate insertion of the shaft member and a locked position in which the sleeve limits radial expansion of the ring. The coupling is suitable for conducting members of a high tension ignition circuit of an internal combustion engine. <IMAGE>
