An electrical connector (10) of elongate shape includes a main body (11) having a first end region (18) which includes one or more electrical contacts in use for contact with a complementary connector component and a second end region (24) opposite the first end region and from which depends a protective guide (12) through which a flexible conductor may extend, the main body of the connector including a locking mechanism (20) whereby, in use, the connector (10) may be selectively releasably secured to a complementary connector component, and the connector (10) including a release control (14) operable to act on the locking mechanism and allow release of the connector from the complementary connector component, wherein the release control (14) is operable at a position further from the first end (18) of the connector than the second end (24) as considered in the direction of the length of the connector.
