Multi-directional mounting unit for mounting a bicycle lock on a tubular frame

A multi-directional mounting unit for mounting a bicycle lock on a tubular frame, said bicycle lock including an elongated lock body and a U-shaped shackle, said mounting unit comprising:

• a tubular mounting part formed with an axially extending slit and a spaced pair of outward flanges disposed on two sides of said slit, said mounting part further having a screw fastener that extends across said outward flanges so as to secure tightly said mounting part on said tubular frame;
• and
• a separate tubular retaining part which confines a receiving space to receive one end of said lock body therein, said retaining part having a retaining notch that extends from a top edge to an intermediate part thereof, each of two opposite side walls that confine said retaining notch being provided with a spaced pair of rounded stop projections for retaining said shackle in said retaining notch;
• one of said mounting part and said retaining part having an outer wall surface which is formed with at least one axially extending positioning rail that confines a longitudinal slide groove therein;
• the other one of said mounting part and said retaining part having an outer wall surface which is formed with at least one axially extending insert projection, a selected one of said insert projections being inserted into a selected one of said positioning rails so as to secure said retaining part on said mounting part.
