Abstract: A connector configured to be connected to an object includes: an electric wire with a terminal; a housing; a shield shell; and a fixing element. The fixing element is fixed to the shield shell and protrudes toward a front side. In a state of the fixing element being inserted in a guiding section in the object, displacement of the fixing element along an axial direction is limited. An end of the fixing element oriented toward the front side is located further toward the front side than ends of the housing and the shield shell oriented toward the front side.

Abstract: A connection structure is a structure for connecting a housing and a cover. In the cover, an engagement portion which protrudes from a main body portion disposed in an opening of the housing is provided. The engagement portion includes a first protruding portion protruding to an outside in an inside-outside direction and a second protruding portion continuing with the first protruding portion to extend in a front-rear direction. In the housing, an accommodation groove for accommodating the engagement portion is provided. The accommodation groove includes a first groove extending in the inside-outside direction and a second groove continuing with the first groove to extend in the front-rear direction. In a state in which the housing and the cover are connected, the first protruding portion is accommodated in the first groove, and the second protruding portion is accommodated in the second groove.
