1. An electrical coupling mechanism for use in electronic devices including watches, calculators, combinations thereof, and the like, adapted for wear on a wearer'"'"'s person comprising a stiff electrical termination, flexible electric circuitry adapted to be coupled thereto, and including elastomeric dielectric insulation, each said termination and said circuitry having bared conductive material thereon, a substantially rigid elongated clip of resilient material having a generally C-shaped cross-sectional configuration and including means for guiding said flexible circuitry around the termination, for bringing the respective bared conductive materials of the flexible circuitry and the termination into electrical contact, for exerting substantially straight-line pressure on said electric circuitry and thereby for mechanically clamping the flexible circuitry and the termination together, said elastomeric dielectric insulation serving as a local equalizer of any thickness variations between said electric circuitry and said termination, and bevelled sides on said clip for acting at least as said guiding means and for enabling said clip to be engaged with said circuitry and said stiff termination in an edgewise sliding manner.
