1. A cylinder lock comprising: a housing with an opening for receiving a lock cylinder with a radially protruding cam;a bolt pivotally moveable by means of said lock cylinder between a retracted position with respect to said housing, wherein the cylinder lock is in an unlocked state, and an extended position with respect to said housing, wherein the cylinder lock is in a locked state;a ring comprising a radial opening for engaging said radially protruding cam, so as to couple said ring and said radially protruding cam, and a toothed arc with a first end and a second end, wherein said first end is adjacent to said radial opening;a slider, coupled between said bolt and said ring and comprising a toothed rack for engagement with said toothed arc, and a recess adjacent to said toothed rack for engagement with said radially protruding cam,wherein said housing comprises at least one guide for guiding said slider between a first position holding the bolt in said retracted position and a second position holding the bolt in said extended position, said ring and said slider being arranged so that, when moving the slider from said first to said second position by rotating said ring by means of the radially protruding cam of the lock cylinder, the radially protruding cam comes to engage the recess in the slider to push said slider towards its second position after which the toothed arc comes to engage the toothed rack of the slider to continue displacing the slider towards its second position so that the radially protruding cam rotates out of engagement with the recess in the slider and vice versa when moving the slider from said second to said first position by rotating said ring by means of the radially protruding cam of the lock cylinder, the toothed arc comes to engage the toothed rack of the slider to push said slider towards its first position after which the radially protruding cam comes to engage the recess in the slider to continue displacing the slider towards its first position so that the toothed arc rotates out of engagement with the toothed rack of the slider;wherein said ring comprises a raised flank extending over a second arc of said ring next to said second end of the toothed arc;wherein said slider comprises a stop opposable to said raised flank of the ring in said second position of the slider so that the raised flank prevents the return of the slider towards said first position; andwherein said recess in the slider has a flank which is opposable to said raised flank of the ring in said first position of the slider so that the raised flank prevents the return of the slider towards the second position. 2. The cylinder lock according to claim 1, wherein said at least one guide comprises at least one end stop. 3. The cylinder lock according to claim 1, wherein said slider further comprises, adjacent to said recess and oppositely located to said toothed rack, a groove for allowing the passage of said raised flank of the ring in said first position of the slider. 4. The cylinder lock according to claim 1, wherein said slider presents a slider cam for engaging a recess in said bolt so as to pivot said bolt between said retracted and extended positions. 5. The cylinder lock according to claim 1, wherein said bolt is hook-shaped. 6. The cylinder lock according to claim 1, further comprising a detent mechanism for marking said first and/or second position of the slider. 7. The cylinder lock according to claim 6, wherein said detent mechanism comprises a spring-loaded detent member fixed to said slider, and at least one recess in said housing for receiving said spring-loaded detent member when the slider is in said first and/or second position. 8. The cylinder lock according to claim 1, further comprising a latch spring-loaded towards an extended position. 9. The cylinder lock according to claim 8, wherein said latch is also connectable to said radially protruding cam, so as to be retractable against said spring load by rotation of said radially protruding cam. 10. The cylinder lock according to claim 8, wherein said latch is also connected to a handle shaft, so as to be retractable against said spring load by rotation of said handle shaft.
