Connector

A connector, comprising:

• a housing (10) including a deflectable lock arm (15), the housing (10) being held connected to a mating housing (90) by the lock arm locking a lock (93) of the mating housing (90);
• and
• a detector (11) movable in a front-rear in the housing (10) direction, the detector (11) being allowed to move from a standby position to a detection position when the housing (10) is properly connected to the mating housing (90), wherein the detector (11) includes:
• two side walls (53) facing each other in a width direction with the lock arm (15) therebetween;
• a detecting body (42) assembled with the lock arm (15) between the side walls (53), the detecting body (42) being tiltable together with the lock arm (15);
• and
• couplings (59) having tilting fulcrums (66) configured to be deformed resiliently when the detecting body (42) is tilted, the couplings (59) extending in oblique directions intersecting the width direction from the side walls (53) to corresponding side surfaces of the detecting body (42).
