[0037] En primer lugar, el usuario agarra el mango 58 de la palanca 50 y empuja el mango hacia el cuerpo de base 14. Consecuentemente, primero la extremidad libre de la protuberancia 56 se aplica contra la superficie de apoyo 48 y despues, por compresion del elemento elasticamente deformable 42 bajo la accion de la clavija de apoyo[0037] First, the user grabs the handle 58 of the lever 50 and pushes the handle towards the base body 14. Consequently, first the free end of the protuberance 56 is applied against the support surface 48 and then, by compression of the elastically deformable element 42 under the action of the support pin

25 54, el tornillo 20 y el pasador de cierre 16 se desplazan a lo largo del eje X-X hacia el lado interior I. Este desplazamiento se hace contra el empuje de los medios de empuje 40.25 54, the screw 20 and the locking pin 16 move along the X-X axis towards the inner side I. This displacement is made against the thrust of the pushing means 40.

[0038] Cuando la fuerza aplicada sobre el mango es suficientemente importante para alcanzar la fuerza de desbloqueo, el pasador de cierre 16 toma su posicion de desbloqueo en la que esta axialmente separado de los[0038] When the force applied on the handle is sufficiently important to reach the unlocking force, the closing pin 16 takes its unlocking position in which it is axially separated from the

30 topes de bloqueo 32. En esta configuracion, los topes de bloqueo 32 no se oponen a una rotacion del pasador de cierre 16 hacia su posicion de liberacion. Esta posicion se muestra en la figura 4.30 locking stops 32. In this configuration, the locking stops 32 do not oppose a rotation of the locking pin 16 towards its release position. This position is shown in Figure 4.

[0039] Despues, manteniendo la presion sobre los medios de empuje 40, el usuario gira la llave 52 alrededor del eje X-X, llevando as! el pasador de cierre 16 a su posicion de liberacion. Esta posicion se muestra en la figura 5.[0039] Then, keeping the pressure on the pushing means 40, the user turns the key 52 around the X-X axis, thus carrying! the locking pin 16 to its release position. This position is shown in Figure 5.

[0040] El cierre se efectua en sentido inverso de las etapas antes mencionadas.[0040] The closure is carried out in the opposite direction of the aforementioned steps.

[0041] El dispositivo segun la invencion es particularmente simple dado que los medios de empuje 40 pueden[0041] The device according to the invention is particularly simple since the pushing means 40 can
