The first connector (2) has an engagement groove (7) and retaining projections (8) provided at a front end portion thereof. The second connector (3) includes a housing body (4) and a slider (5) slidably mounted within the housing body (4). The housing body (4) includes an elastic lock arm (10) having at its front end a lock portion (9) for engagement in the engagement groove (7), and the slider (5) is resiliently urged in an axial direction, and has an elastic cantilever arm (12), and abutment portions (11) for abutting engagement respectively with the retaining projections (8) are formed at a front end of the cantilever arm (12). An abutment surface of each retaining projection (8) are both formed into substantially-arcuate surfaces, substantially disposed on an imaginary circle (A) having its center disposed on an axis (C) of flexing of the cantilever arm (12).
