Abstract: The invention relates to a coaxial connector for connecting a coaxial cable to a printed electronic-circuit board. The connector element intended to be attached to the printed board is arranged as a cylindrical socket (1) comprising an external bush (3) provided integrally at its rear portion with means (5) for attaching it to a printed board, and a central contact (9) provided integrally at its rear portion with means (12) for attaching it to said printed board; the connector element intended to be fixed to the coaxial cable is arranged as a plug (2) comprising a tubular portion (16) for connection to the end of a coaxial cable and a tubular coupling portion (15) comprising a cylindrical external bush (22), and a central contact (26) comprising at its rear portion connection means (27) for the central conductor (17) of the coaxial cable, said central contacts of the two connector elements comprising interacting means (14, 30) for locking by snap-fastening.
