An interlocking connector system includes two connector members that can each be mounted to separate objects and then interlocked together to attach the two objects together. In one embodiment, the two connector members are identical and interchangeable with each other. In other embodiments, the two connector members are arranged to attach together objects having perpendicular mounting surfaces or coplanar mounting surfaces. The connector members include an alignment structure having a projection positioned between a first pair of inclined surfaces, and a receiver structure positioned between a second pair of inclined surfaces. The connector members are interlocked together by mating the alignment structure of one connector member with the receiver structure of the other connector member. The relative movement between the connector members causes the inclined surfaces of one connector member to wedge against the inclined surfaces of the other connector member to form a tight and strong connection.

A clipless mechanism for a four-sided clipless bicycle pedal is made by a stamping and welding process. The stamping is preferably a progressive stamping process. The stamped parts include two components, an inner wing and an outer wing. The two stamped components are generally similar in shape to each other, but the inner wing fits within the outer wing. Each part is first stamped as a flat pattern by a progressive die. Each part then has radii stamped into the edges by the second station of the progressive die. Next, each part is partially folded by the third station of the progressive die. Then each part is folded completely by the fourth station of the progressive die. The actual number of steps may vary depending upon the material chosen, the thickness of the material and the design of the stamping tool. Then each part is welded closed and the resulting rectangular wings are assemblied in juxtaposed orthogonal relation to provide four shoe cleat engaging receptacles.
