A connector is provided having functions for sensing the half-fitted state and improved compactness and workability through a simple construction with few components. The connector includes: a first connector part ( 2 ) having a first housing fitted with a contact pin; a second part ( 21 ) having a second housing with a contact pin connecting with the aforesaid one; and a rotating ring ( 15 ) fitted rotatably to the first or second housing and having locking legs ( 161 ) that lock coupling of the two parts. On rotating ring ( 15 ), a latching section ( 181 ) that inhibits the rotation of the rotating ring and housing where the rotating ring is fitted is provided. Prior to coupling of the two parts, the rotating ring ( 15 ) is latched to the housing by the latching sections. During mating-coupling, anti-rotation is terminated by the other part being pushed in, the rotating ring ( 15 ) is free to rotate, and coupling of the two parts is locked by the locking legs ( 161 ).
