Lever latch for locking a leaf, which comprises a support body (2) susceptible of being embedded in a shaped cavity of a leaf, and provided with a guide (7) having at one end an outlet opening (70). The latch (1) also comprises an actuation lever (8), hinged to the support body (2) by means of a first pin (9) engaged at its ends in opposite seats (10), made on the lateral walls (3,4) of the support body (2). Then, an elongated plate-like spring (11) is provided which is engaged at a first end (11A) with a second pin (12) mechanically associated with the aforesaid actuation lever (8), and a locking rod (13) is also provided, slidably engaged in the guide (7) of the support body (2), and provided with a first free termination (13A) susceptible of being engaged in a hole of a fixed frame or of a floor and with a second termination (13B) fixed to the second end (11B) of the elongated plate-like spring (11). The actuation lever (8) is then manually actuatable to rotate around the first pin (9) between a first angular end stop position (A), in which the locking rod (13) projects from the outlet opening (70) of the guide (7), and a second angular end stop position (B), in which the locking rod (13) is more retracted in the guide (7). The lateral walls (3, 4) of the support body (2) are provided with a plurality of opposite seats (10) that are aligned along the longitudinal direction (Y) of the same support body (2), and are susceptible of selectively receiving the ends of the first pin (9) in order to vary the position of the actuation lever (8) and of the locking rod (13) along the longitudinal direction (Y) of the support body (2).
