Connector

A connector comprising:

• a plurality of terminals;
• a housing having a tubular outer wall part, a holding part extending along an axial direction of the outer wall part and having a plurality of terminal housing chambers, lances supported on the outer wall part and positioned radially outside the respective terminal housing chambers, and a locking part;
• and
• a detection member having a tubular fitting part to be fit to the holding part along the axial direction and an engaging part to be engaged with the locking part, wherein
• the terminal housing chambers are disposed along a circumferential direction around a center line of the housing,
• the lances, when the respective terminals are inserted into a regular position in the respective terminal housing chambers, are engaged with the respective terminals to lock the respective terminals and, when the fitting part is fit to the holding part, enter an inside of the fitting part to allow the engaging part to be engaged with the locking part, and
• the lances, when the respective terminals are not inserted into the regular position, are pressed by the respective terminals to become deformed radially outward and to lock the fitting part at a first position, the first position being short of a position at which the engaging part is engaged with the locking part.
