1. A lock for a sliding door or gate comprising:a frame; a latch bolt comprising a shaft portion and at least one laterally projecting wing on the shaft portion, the shaft portion projecting in a predetermined direction out of the frame and being rotatably mounted on the frame according to a rotation axis extending in said predetermined direction; and a latch bolt operating mechanism arranged to rotate the latch bolt from a first angular orientation, wherein the lock wing of the bolt is in a locking position, to a second angular orientation, wherein the lock wing of the bolt is in an unlocking position and vice versa, the latch bolt operating mechanism comprising a resilient element arranged to urge the latch bolt from its second to its first angular orientation, said wing having a lateral surface defining a screw-like curve around the rotation axis of the latch bolt enabling to convert a translational motion of the latch bolt in said predetermined direction into a rotational motion of the latch bolt from its first to its second angular orientation and said screw-like curve having a pitch greater than 150 mm. 2. The lock according to claim 1, wherein the lock wing is arranged to secure the latch bolt through a slot in a reception element, the lock wing being arranged to rotate the latch bolt to said second angular orientation by co-operating over said screw-like curve with an edge of said slot when being inserted in this slot.3. The lock according to claim 1, wherein the lateral surface of the lock wing is plough-shaped.4. The lock according to claim 1, wherein the bolt comprises two laterally projecting lock wings which project in opposite directions.5. The lock according to claim 4, wherein the laterally projecting lock wings are substantially propeller shaped.6. The lock according to claim 1, wherein the screw-like curve has a pitch greater than 180 mm.7. The lock according to claim 1, wherein the screw-like curve has a pitch smaller than 350 mm.8. The lock according to claim 1, wherein the lock further comprises means for mounting at least one hand operated actuating element for said latch bolt operating mechanism on the frame so that the actuating element can rotate on the frame according to a further rotation axis forming an angle with the rotation axis of the latch bolt.9. The lock according to claim 8, wherein the further rotation axis is substantially perpendicular to the rotation axis of the latch bolt.10. A lock for a sliding door or gate comprising:a frame; a latch bolt comprising a shaft portion and at least one laterally projecting wing on the shaft portion, the shaft portion projecting in a predetermined direction out of the frame and being rotatably mounted on the frame according to a rotation axis extending in said predetermined direction; a latch bolt operating mechanism arranged to rotate the latch bolt from a first angular orientation, wherein the lock wing of the bolt is in a locking position, to a second angular orientation, wherein the lock wing of the bolt is in an unlocking position and vice versa, the latch bolt operating mechanism comprising a resilient element arranged to urge the latch bolt from its second to its first angular orientation, and means for mounting at least one hand operated actuating element for said latch bolt operating mechanism on the frame so that this actuating element can rotate on the frame according to a further rotation axis forming an angle with the rotation axis of the latch bolt, wherein said wing has a lateral surface defining a screw-like curve around the rotation axis of the latch bolt enabling to convert a translational motion of the latch bolt in said predetermined direction into a rotational motion of the latch bolt from its first to its second angular orientation and wherein said means for mounting the hand operated actuating element on the frame comprise a follower which is rotatably mounted according to said rotation axis onto the frame, and said bolt operating mechanism comprises a first latch bolt lever mounted irrotatably onto the follower and a second latch bolt lever which can rotate independently from the follower according to said rotation axis between a first angular orientation and a second angular orientation, the second latch bolt lever having a first crown wheel portion and the latch bolt a second crown wheel portion engaging the first crown wheel portion so that when the second latch bolt lever is in its first angular orientation, the latch bolt is also in its first angular orientation and when the second latch bolt lever is in its second angular orientation, the latch bolt is also in its second angular orientation, the first and second latch bolt levers being provided with mutually co-operating abutment means enabling to rotate the second latch bolt lever from its first to its second angular orientation by rotating the first latch bolt lever and to rotate the second latch bolt lever from its first to its second angular orientation by rotating the latch bolt without rotating the first latch bolt lever.11. The lock according to claim 10, wherein the lock comprises a key actuated cylinder provided with a rotary driving bit and a retaining element movable by means of the rotary driving bit between a first position wherein the retaining element engages the first latch bolt lever to obstruct a rotation motion thereof and a second position wherein the retaining element enables the rotation of the first latch bolt lever.12. A The lock according to any one of claims 1, 10 or wherein said latch bolt is made of at least a first and a second part which are removably fixed to one another, the first and second parts being provided with a screw thread by means of which they are screwed onto one another, the first part comprising at least a head portion which has said lock wing and a part of the shaft portion whilst the second part comprises a part of the shaft portion which is rotatably mounted in the frame and which projects over a distance out of the frame.13. A lock for a sliding door or gate comprising:a frame; a latch bolt comprising a shaft portion and at least one laterally projecting wing on the shaft portion, the shaft portion projecting in a predetermined direction out of the frame and being rotatably mounted on the frame according to a rotation axis extending in said predetermined direction; and a latch bolt operating mechanism arranged to rotate the latch bolt from a first angular orientation, wherein the lock wing of the bolt is in a locking position, to a second angular orientation, wherein the lock wing of the bolt is in an unlocking position and vice versa, the latch bolt operating mechanism comprising a resilient element arranged to urge the latch bolt from its second to its first angular orientation, wherein said wing has a lateral surface defining a screw-like curve around the rotation axis of the latch bolt enabling to convert a translational motion of the latch bolt in said predetermined direction into a rotational motion of the latch bolt from its first to its second angular orientation and wherein the shaft portion of the latch bolt has an end portion by means of which the latch bolt is rotatably mounted in the frame, which end portion is provided with a collar engaging the back side of a cover plate of the lock through which the latch bolt projects out of the frame, the collar being maintained in a circumferential groove formed between the cover plate and a further frame element which is rigidly united with the cover plate so that the latch bolt is secured between the cover plate and the further frame element and rotates in the cover plate and in the further frame element when rotating between said first and second angular orientations.14. The sliding door or gate provided with a lock according to any one of the claims 1, 10 or 13, further comprising a bolt reception element for receiving and securing the latch bolt of the lock in a locking position, said bolt reception element having a slot having a width that the latch bolt can be guided through the slot in its second angular orientation but that, in the first angular position of the bolt, the lock wing secures the latch bolt behind the slot in the reception element.15.
