A bicycle lock according to the invention comprising a receiving part into which a locking pin (5) may be inserted and locked by means of a pawl (8) capable of engaging a recessed groove (6) in the locking pin (5). The pawl (8) is part of a bent spring member (7) and is the only part in the resilient pawl system. A pin (13) mounted eccentrically at the end of the locking cylinder (12) will be capable of lifting the pawl (8) out of its locking engagement in the locking pin (5) by rotation. Since the spring element thus forms both the resilient part and the pawl part, the structure may be made compact and thus constitute a stable pattern of movement. This minimizes the risk of locking failure because of play, spring breakage or natural oscillations. The receiving part moreover accommodates a cover plate (16) at the bottom of the housing (3) to protect the groove (5) of the locking pin (6) and to protect against rotation of the locking cylinder in the receiving part.
