Abstract
A mechanism for connecting and disconnecting, locking and unlocking, and holding members to one another, including snap-on fasteners, and at the same time providing mechanical, electromagnetic shielding, electrical conductivity, and thermal dissipation, coupled with environmental sealing, is provided by a cylindrical or elliptical body having a circumferential groove therein and a continuous coil spring disposed therein. A housing, having a bore sized to accommodate the cylindrical, or spherical, body, is provided, and a tapered bottom in the circumferential groove prevents the spring from turning past a vertical line, thus locking or connecting the cylindrical, or spherical, member with the housing or plate.
