Wheel-locking device, in particular for a pram, which includes at least one wheel unit (4) and a wheel-locking member capable of being displaced substantially parallel to the axle of the wheel and of coming into contact with the wheel rim in order to lock its rotational position, wherein the wheel unit (4) is linked to the frame of the pram by means of a vertical linking sleeve (12) and in that the locking member includes a movable finger (14a, 14b) actuated by a control shaft (15) which moves vertically inside the linking sleeve. A single action on the flexible rod 18 therefore simultaneously locks the two pivoting wheel units of the axle beam 3 in terms of rotation. In one embodiment, the same wheel units may be locked in a fixed direction by means of locking parts (32, 33) interacting with the notches (30) of the linking sleeve (12).
