A molded plastic rivet for affixing two parts to each other when the rivet is inserted through two mutually aligned apertures in the parts. The rivet includes a pin having a pin head, a pin shank and first and second pin latching offsets at the distal end of the pin shank. The latching elements include at least first latching offsets. The rivet also includes a rivet body having a rivet body head, and a rivet body shank that is insertable in the apertures and comprises several legs running away from the head of the rivet body, these legs being joined to each other distally into a nose tapering toward the longitudinal axis of the rivet body, a passage being formed between the legs and passing through the head of the rivet body, each leg being fitted at a distal end thereof with a first locking surface element facing the passage for engaging the first latching offsets of the pin once the pin has been driven completely into the rivet body, where, in a pre-assembled state, the pin shank is partly insertable into said passage, the legs running radially outward to the rivet body's longitudinal axis, each leg being fitted at a proximal end thereof with a second locking surface element engageable with the first latching offsets of the pin in the pre-assembled state, wherein approximately diametrically opposite protrusions are configured on the side of the head of the rivet body at regions opposite the shank of the rivet body and are fitted with recesses or apertures for receiving respective arms of a fork-shaped assembly tool.
