The lock comprises two elements (44 and 45) which hook together, one of which constitutes a closure member (48) and the other a holding part (50), and which are pressed together by a return spring (55), so that in combination the pressure exerted by the said spring tends to complete the closure of the leaf. This lock furthermore comprises a cam (58) carried by the same support [stationary framework (45) and leaf (44)] as the holding part (50), and which acts during closure of the leaf on the closure member (48) so as to press it against the holding part. <IMAGE>
