The device comprises a hook ( 2 ) connected to the door ( 5 ) and a support structure ( 1 ) in which is defined an aperture ( 4 ) for the introduction of the hook ( 2 ) and in which are mounted: a rotatable member ( 6 ) biased by a spring ( 12 ) and operable to retain a hook in a closure position of the door ( 5 ) and to release this hook ( 2 ); and a control device ( 14 - 16 ) including a pawl ( 15 ). When, with the door ( 5 ) closed, a force is applied to the hook ( 2 ) in the direction such as to open the door ( 5 ), the rotatable member ( 6 ) is initially free to turn, against the action of the spring ( 11 ), with respect to an auxiliary body ( 9 ), to a position in which the rotatable member ( 6 ) releases the auxiliary body ( 9 ) from the pawl ( 15, 19 ), and then to turn, together with the auxiliary body ( 9 ) and under the action of the spring ( 11 ), to release the hook ( 2 ).
