Grommet protective member and electrical wire connection device

A grommet protection member configured to be attached to an end portion of a grommet made of a soft material, the grommet being configured to come into direct contact with an outer circumferential surface of an attachment member, wherein:

• the grommet protection member is made of a material that is harder than the soft material of the grommet and is attached to surround, from an outer circumferential surface side, an end portion of the part of the grommet that is fitted to the attachment member,
• a flange is integrally formed on an inner circumferential surface of the grommet protection member projecting therefrom, the flange compressing the grommet along an entire outer circumference of the grommet, wherein the flange compresses the grommet at a portion having a circumference that is narrower than a circumference of a main portion of the grommet, and
• the grommet protection member defines a first planar portion and a second planar portion, the flange projecting from a center portion of the grommet protection member between the first planar portion and the second planar portion to form a peak, the peak extending radially inward with regard to the first planar portion and the second planar portion, and the grommet protection member contacting the grommet only at the peak.
