ABSTRACT A locking attachment for an adjustable height bicycle type saddle assembly having a seat post tele- scopically adjustable in an upstanding tubular seat mast. The tubular wall of the seat mast has a pair of diamet- rically opposed apertures one of which is internally screw threaded. A plurality of holes are spaced apart along the seat post and are selectively registrable with the apertures at different adjusted heights of the saddle assembly. A separable, unitary locking member comprises a forwardly extending lock pin, an externally screw-threaded collar with a forwardly facing shoulder, and a manually rotatable knob. In the locked position, the lock pin extends through a selected seat post hole into the seat mast aperture opposite the threaded aperture, the screw-threaded collar threadedly engages the screw-threaded aperture, the shoulder frictionally engages the outside of the seat post wall, and the knob provides an external handle for rotating the locking member to and from its locked position.
