Abstract: A releaseable multi-channel electrical connector is designed for small size, and ease of use without generating manipulation forces that might be transmitted to an attached living subject. Two pivoting frame members on which electrical snap connectors are mounted are oriented such that the two snap connectors face a male connector element placed between the two frames.
