A connector, comprising: a housing which is internally formed with one or more terminal accommodating chambers and from a rear end surface of which one or more wires are to be drawn out; and a wire cover to be mounted on an outer periphery of a rear end portion of the housing to at least partly surround the wires; an area of the rear end surface of the housing at an outer edge side of a draw-out area for the wires serving as at least one operation surface used to push the housing forward, wherein: an area of the outer periphery of the rear end portion of the housing before the operation surface is recessed to form at least one locking recess; the housing is formed with at least one bored portion by further recessing a part of a back surface of the locking recess; at least one locking projection for engagement with the locking recess is formed on the inner surface of the wire cover; the locking projection is formed with at least one restricting projection for preventing displacements of the wire cover relative to the housing in an assembling direction substantially parallel to the operation surface by being engaged with the bored portion; and the restricting projection comprises a restricting surface substantially perpendicular to the assembling direction of the wire cover; characterized in that a guiding inclined surface oblique to the assembling direction of the wire cover is formed in an area which is located, in the assembling direction, in an area below the restricting surface out of a surface of each restricting projection substantially facing a groove bottom surface of the locking recess. a housing which is internally formed with one or more terminal accommodating chambers and from a rear end surface of which one or more wires are to be drawn out; and a wire cover to be mounted on an outer periphery of a rear end portion of the housing to at least partly surround the wires; an area of the rear end surface of the housing at an outer edge side of a draw-out area for the wires serving as at least one operation surface used to push the housing forward, wherein: an area of the outer periphery of the rear end portion of the housing before the operation surface is recessed to form at least one locking recess; the housing is formed with at least one bored portion by further recessing a part of a back surface of the locking recess; at least one locking projection for engagement with the locking recess is formed on the inner surface of the wire cover; the locking projection is formed with at least one restricting projection for preventing displacements of the wire cover relative to the housing in an assembling direction substantially parallel to the operation surface by being engaged with the bored portion; and the restricting projection comprises a restricting surface substantially perpendicular to the assembling direction of the wire cover; an area of the outer periphery of the rear end portion of the housing before the operation surface is recessed to form at least one locking recess; the housing is formed with at least one bored portion by further recessing a part of a back surface of the locking recess; at least one locking projection for engagement with the locking recess is formed on the inner surface of the wire cover; the locking projection is formed with at least one restricting projection for preventing displacements of the wire cover relative to the housing in an assembling direction substantially parallel to the operation surface by being engaged with the bored portion; and the restricting projection comprises a restricting surface substantially perpendicular to the assembling direction of the wire cover; characterized in that a guiding inclined surface oblique to the assembling direction of the wire cover is formed in an area which is located, in the assembling direction, in an area below the restricting surface out of a surface of each restricting projection substantially facing a groove bottom surface of the locking recess.
