To prevent a removing tool from being shifted in the width direction of control equipment when the control equipment mounted on a sockets is pulled out by engagingly fitting the pawls at the tip end of both foot parts.

Protrusion stripes 8 for guiding connection to control equipment 6 of a removing tool 1 with the stripe engagingly fitted to slits 4 of pawls 2a of the removing tool 1 are so provided as to form a T shape on the lower side of fitting protrusions 7 to which the pawls 2a are fitted. Thereby, since the protrusion stripes 8 are kept to be fitted to the slits 4 even in a state in which the pawls 2a are fitted to the fitting protrusions 7, the removing tool 1 is certainly positioned in the width direction toward the control equipment 6, and the adjacent control equipment 6 is not pulled out together due to shifting.
