A connector includes: a housing; and a cover. The housing includes a lock body that is lockable to a counterpart lock body so that fitting connection with the counterpart housing is not canceled, and a lock cancellation arm that deforms with application of lock cancellation force to a point-of-effort part and cancels a state in which the lock body is lockable to the counterpart lock body. The cover includes a second wall that covers the housing up to the position of the point-of-effort part in the fitting connection direction, an exposure part formed at the wall to expose the point-of-effort part, and a lock cancellation operation body that includes an operation part capable of receiving a press movement operation, blocks the exposure part to an extent that deformation along with the press movement operation is possible, and applies the lock cancellation force to the point-of-effort part through the deformation.
