A conveyor belt assembled of modular plastic components is retained together without the usual connecting rods or pins. In one embodiment the modules, each of which has series of finger-like projections or knuckles both at forward and rear ends of the module, the projections are tapered to narrows in width from top to bottom. The projections at either the forward or rear side have laterally extending posts or dowels at one side of each projection, each with a length that extends through only part of the width of the gap between adjacent projections. In the opposite set of projections are holes, similar to the aligned holes that are present when module rows are connected by rods. With the projections being tapered, modules of adjacent rows can be put together by interdigiting the projections with the modules of adjacent rows held at an angle, preferably an acute angle beyond 90°. When the modules are brought back toward alignment to a common plane, the pivot posts of one module become locked in the holes of the module of the adjacent row.
