Electrical connector with sliding fitting detection member

A connector comprising:

• a housing configured to be fitted to a counterpart housing and having a terminal accommodating chamber configured to accommodate a terminal;
• and
• a fitting detection member slidably attached to the housing and configured to detect fitting between the housing and the counterpart housing,
• wherein the fitting detection member includes a locking protrusion to be locked to a locked protrusion of the housing,
• wherein, when the locking protrusion is locked to the locked protrusion, the locked protrusion of the housing prevents the locking protrusion of the fitting detection member from moving in a rear direction,
• wherein in the housing, a space configured to allow the locking protrusion to pass in a sliding direction of the fitting detection member is defined between an outer peripheral surface of the housing and the locked protrusion,
• wherein the locking protrusion passes through the space from a rear end toward a front end in the sliding direction and is locked to the locked protrusion,
• wherein the housing includes a locking mechanism configured to be locked with the counterpart housing in a state where the housing and the counterpart housing are fitted to each other,
• wherein the locking mechanism includes:
• a pair of left and right elastic arm pieces that are supported on the outer peripheral surface of the housing in a cantilever manner and extend forward;
• a locking piece that bridges front end portions of the pair of left and right elastic arm pieces in a left-right direction and that is locked with the counterpart housing in the state where the housing and the counterpart housing are fitted to each other;
• a pair of left and right release arms that are supported on the front end of the pair of right and left elastic arm pieces in a cantilever manner, respectively, and extend rearward, and
• wherein the locked protrusion is provided at a central portion, in an extending direction, of each of the release arms.
