An attachment ( 10 ) for preventing a cover ( 4 ) from falling off from a housing ( 1 ) is provided. The cover ( 4 ) includes an elastic member ( 54 ) on each of the right and lefts ends thereof. The elastic members are made elastically deformable by forming slits ( 56 ) in the cover ( 4 ). The elastic members ( 54 ) each have a protrusion ( 52 ). In order to mount the cover ( 4 ) to the housing ( 1 ), the protrusions ( 52 ) are inserted into respective ones of holes ( 7 ) formed in the housing ( 1 ) by inwardly deforming and, then, restoring the elastic members ( 54 ). After mounting the cover ( 4 ) to the housing ( 1 ), the cover falling-off preventing attachment ( 10 ) is attached to the cover ( 4 ), with side walls 18 of the attachment ( 10 ) positioned to extend into the respective slits ( 56 ), whereby the deformation of the elastic members ( 54 ) is prevented.
