A coupling apparatus (10) includes a first coupling element (12) and a second coupling element (14). The first coupling element (12) has a mating surface (16) and a wedging surface (22) at the first end (18) of the first coupling element (12). An engagement surface (30) is located at the second end (20) of the first coupling element (12) and an alignment orifice (32) extends through the first coupling element (12). A second coupling element (14) also includes a mating surface (46) and a wedge member (48) at the first end (42) of the second coupling element (14). This wedge member (48) engages the wedging surface (22). An alignment member (60) at least partially extends through the alignment orifice (32), and a locking tab (62) extends from the second coupling element mating surface (46) and engages the engagement surface (30).
