An electrical connector A has a connector housing (10) with a locking arm (11) formed integrally with an outer surface of the connector housing(11). A thickness Tk of a base part (12) of the locking arm (11) is set larger than a thickness Ta of an arm part (13) thereof. Thus, the flexure rigidity of the base part (12) is greater than that of the arm part (13). When the locking arm (11) tilts in away from the connector housing (10), with the base part (12) acting as the supporting point of the tilting motion of the locking arm (11), the degree of the strain of the base part (12) is low. This is because the base part (12) is less flexible than the arm part (13). A force of tilting the locking arm (11) is relaxed by elastic deformation of the arm part (13), which is more flexible than the base part (12). A stress generated by the tilting of the locking arm (11) does not concentrate on the base part (12), but is dispersed in the arm part (13). Thus, it is possible to prevent the base part (12) from being broken.
