A steering lock for a bicycle comprises first and second tube members (3 and 12) disposed co-axially and arranged for relative rotation about a common axis. Coupling means in the form of roller formations (14) are provided for coupling the first and second members (3 and 12) together so that steering movement of the handlebars can be transmitted to the bicycle fork, and lock-operated means, including a cam (8), is provided for deactivating the coupling means (14) so that steering movement of the handlebars is not transmitted to the bicycle fork. The outer tube member (3) comprises a bush formed with axially extending grooves (3A) of substantially semi-circular cross-section to receive the roller formations (14) and the bases of the grooves (3A) are formed with rebates (3B).
