An attachment connection (18) for securing a vehicle trim component (16) to a vehicle body sheet metal panel (20) includes an attachment projection (22) extending from the trim component with an attachment formation (24) molded in situ thereon from a softer material. An opening (26) in the sheet metal panel (20) includes a cantilevered leaf spring (28) having a terminal end (30) that is engaged with the softer attachment formation (24) upon insertion of the attachment projection into the opening to thereby provide securement of the trim component. The leaf spring (28) has a curved section (32) to provide enhanced spring action thereof and its terminal end (30) preferably has a curved shape that engages the attachment formation (24) on the attachment projection (22). An alternate embodiment has the attachment projection (22) provided with oppositely facing securement portions (42) and the sheet metal panel opening (26′) has a pair of the cantilevered leaf springs (28) whose terminal ends (30) engage the softer material of the oppositely facing securement portions of the attachment formation on the attachment projection.
