The invention relates to a lock, in particular a hoop lock, having a lock housing, in which a locking cylinder of the lock is arranged, including a cylinder housing, a barrel rotatably mounted in the cylinder housing and a driver unit associated in a drive effective manner with the barrel, and having at least one bolt coupled to the barrel via the driver unit, so that by rotating the barrel the at least one bolt is moveable from a locked position into a release position. The lock housing has a receiving space in an axial extension of the locking cylinder, with the locking cylinder or a part thereof being able to be displaced from an operational position into the receiving space on the application of a predefined force in the axial direction of the locking cylinder, to adopt a sabotage position, in which the coupling of the at least one bolt to the barrel is taken out of operation.
