An electrical coupling arrangement, particular for digital transfer, has a female connector and a male connector. Each connector has an electrical coupling portion via which the data are transferred. The connectors are held together by means of a latching arrangement consisting of a pair of fixed latching posts on the male connector which mate with a corresponding pair of flexible latching sleeves which are molded within the body of the female connector. The self-latching action means that the coupling may be effected rapidly but also securely. The invention extends to a method of manufacture, with the body of the female connector being molded around latching sleeves which may have a lower melting point than the material making up the body itself.
