Abstract
A connector waterproofing stopper includes a tubular part which in turn has a seal portion in one half thereof and a connecting portion in the other half thereof. The connecting portion has an annular engaging rib in the end portion of the outer peripheral surface thereof. The annular engaging rib includes an engaging surface and, on the opposite side of the engaging surface, a tapered reinforcing portion which extends from the top portion of the annular engaging rib toward the axial direction of the connecting portion. When an external force to pull an electric wire is given to the annular engaging rib, the reinforcing portion prevents the annular engaging rib from inclining to thereby maintain the engagement between the engaging surface and an electric wire connecting terminal.
