In a combination lock, especially for bicycles, with a bearing projection, with a locking part displaceable in the bearing projection, with a plurality of tumbler rings mounted rotatably in the bearing projection, with locking bits formed on the locking part and with locking-bit passage orifices on each tumbler ring, the combination lock having a device for the rotational blocking of the tumbler rings in their possible rotary detent positions during a displacement of the locking part out of the locking position into a manipulation position, it is proposed that the tumbler rings have radial recesses on an inner circumferential surface at points assigned in each case to the possible rotary detent positions, that the locking part be provided with noses which are matched to the shape of the recesses, precede the respective locking bits in the axial direction and project beyond the circumference of the bearing projection and which, in a rotary detent position of the respective tumbler ring, are out of engagement with the respective recess, when the locking part is in the locking position, and are in engagement with the respective recess, the said engagement blocking the rotation of the respective tumbler pin, when the locking part is in the manipulation position. This results in a particularly compact construction. <IMAGE>
