An attempt to fit an improper combination of housings ( 10, 30 ) together brings a projection ( 32 R) of the wrong housing ( 30 ) into abutting engagement with an interference portion ( 15 ) in a fitting recess ( 12 ). Abutment surfaces ( 15 a , 32 Ra) are inclined in directions to move an inner peripheral surface of the fitting recess ( 12 ) towards an outer peripheral surface of the wrong housing ( 30 ). Therefore, the fitting recess ( 12 ) cannot deform and spread out, and the fitting of the wrong housing ( 30 ) cannot proceed by force.
