A lever-type connector has first and second housings (10, 20) that can be mated with one another. A lever (30) is mounted rotatably on the first housing (10). A cam groove (35) is formed on the lever (30) and engages a follower pin (22) on the second housing (20) to connect the housings (10, 20). The cam groove (35) has steep surface area (45) whose distance from a center of rotation of the lever (30) decreases at a higher rate than the other areas of the cam groove (35) and is formed at a position of the cam groove (35) slightly before a terminus end (35B). Thus, an operation resistance peaks when follower pins (22) reach the steep surface areas (45). This peak operation resistance is larger than a sum of a resistance required to engage a lock (41) with a projection (26) and a connection resistance acting between housings (10, 20).
