Terminal and connector

A terminal that is inserted into a sealing hole of a mat seal of a housing from a rear side to a front side, and that is detached from the front side to the rear side, the terminal comprising:

• a first box portion that is substantially box-shaped,
• wherein the first box portion includes:
• a first bottom wall, a pair of first side walls that stand upright from two ends of the first bottom wall, a first ceiling wall that opposes the first bottom wall, and a locking wall positioned on a rear end side of the first box portion, which is a leading end side in a detaching direction of the terminal,
• the first ceiling wall and the locking wall are connected to each other via a connection portion curved from the detaching direction toward the first bottom wall,
• one of the first side walls has an extended portion extending to the rear side,
• an extending end of the extended portion overlaps a plate surface of the locking wall as viewed from a direction perpendicular to the detaching direction, and
• the locking wall extends from a portion thereof that is coupled to the connection portion to the other first side wall side, and an extended end portion of the locking wall and a rear end edge of the other first side wall oppose each other in a front-rear direction.
