A lever-type connector configured such that a first connector housing and a second connector housing are made connectable and separable by displacing a cam follower provided on the second connector housing along a cam groove formed on a lever as the lever rotatably provided on an outer surface of a main body portion of the first connector housing is rotated between an initial position and a connection end position, comprising: a lock arm provided on the lever such that one end part thereof is deflectable and configured to hold the lever at the connection end position by being locked to the first connector housing when the lever is at the connection end position; a locking projecting edge configured to be locked to a lock protrusion of the lever when the lever is at the connection end position; a first pinching surface; a protecting portion formed on the lever and configured to cover the one end part of the lock arm from a side facing in a deflecting direction of the lock arm; and a second pinching surface is formed on a part of an outer surface side of the protecting portion along the deflecting direction of the lock arm, wherein the second pinching surface is configured to enable the lever to rotate to the initial position by displacing the lock arm in an unlocking direction to release a locking of the lock protrusion and the locking projecting edge by a pinching operation of the first and second pinching surfaces (27, 29) when the lever is at the connection end position, characterized in that the lock arm is provided on the lever such that one end part thereof is deflectable in the deflecting direction which is a direction away from the outer surface, the locking projecting edge is formed to project on the outer surface, and the first pinching surface is formed on a surface of the one end part of the lock arm facing the outer surface. a lock arm provided on the lever such that one end part thereof is deflectable and configured to hold the lever at the connection end position by being locked to the first connector housing when the lever is at the connection end position; a locking projecting edge configured to be locked to a lock protrusion of the lever when the lever is at the connection end position; a first pinching surface; a protecting portion formed on the lever and configured to cover the one end part of the lock arm from a side facing in a deflecting direction of the lock arm; and a second pinching surface is formed on a part of an outer surface side of the protecting portion along the deflecting direction of the lock arm, wherein the second pinching surface is configured to enable the lever to rotate to the initial position by displacing the lock arm in an unlocking direction to release a locking of the lock protrusion and the locking projecting edge by a pinching operation of the first and second pinching surfaces (27, 29) when the lever is at the connection end position, characterized in that the lock arm is provided on the lever such that one end part thereof is deflectable in the deflecting direction which is a direction away from the outer surface, the locking projecting edge is formed to project on the outer surface, and the first pinching surface is formed on a surface of the one end part of the lock arm facing the outer surface.
