A connector (F) has a main body (10) with an outer surface. Shafts (11) project from the outer surface and a retainer (12) projects from each shaft (11). A lever (20) has bearing holes (23) with notches (26) dimensioned to receive one of the retainers (12). The notches (26) align with the retainers (12) in a connection ending position of the lever (20) so that the lever (20) can be mounted rotationally on the main body (10) or removed from the main body (10). A resilient lock (14) presses the lever (20) parallel to the axis of the shafts (11) so that the retainers (12) engage edges of the bearing holes (23) to prevent detachment of the lever (20) from the shafts (11) in other rotational orientations.
