Abstract: A latching mechanism for a top of a motor vehicle which is tightened against a fixed body, includes a support bracket arranged on the side of the top having an operating lever supported about a first transverse axis as well as a pivotal latching member which cooperates with a receiving device on the side of the body. For improving the operating comfort of the latching mechanism, the operating lever is connected with the latching member by way of a guide lever. Furthermore, the latching member cooperates with the support bracket and the receiving means by way of a positive control in such a manner that during the pivoting of the operating lever into its raised locking position, a defined upward movement of the latching member in the direction toward the receiving means and a following tightening movement inside of the receiving means take place.
