Abstract: Electrical connector assembly comprises a housing having a plurality of cavities therethrough and a retainer having a like plurality of cavities therethrough, said housing and retainer being latchably matable so that said cavities and passages are coaxially aligned. Retainer has contact engaging means formed as sets of spring fingers radially arranged about respective passages and extending from the forward face of the retainer to distal ends of the fingers. Each set of fingers defines a first diameter at said forward face and a second smaller diameter toward said sital ends, the fingers spreading apart resiliently as a contact inserted through the passage reaches the smaller diameter, the fingers returning so that the distal ends engage a shoulder on the contact when same is fully inserted.
