Device of the type which comprises a piston part whose rod secures the door to a projection of the frame, characterized in that, unlike existing devices which are mounted in a complicated manner on the outside, becoming damaged by bad weather, the present device avoids such problems by being mounted on the inside on each lateral tubular longitudinal member L of each door p and its piston part 1 being articulated by means of a connecting rod 7 to an intermediate zone of the actuating lever 9 which projects via an aperture a of the longitudinal member 1 to which it is articulated, provision being made on the connecting rod 7 for a keeper 12 which, once the lever 9 has been actuated into its closure position, is secured to it via a slot 11 thereof, ensuring the closure of the device by means of the urging spring 18 of the piston part 1 in its passive retracted position, carrying out a function of tensioning the aforesaid articulated elements. <IMAGE> |
