A chain guide is composed of a resin shoe engageable with an aluminum base frame. The shoe has a hook formed at a chain entry end for engagement with a chain entry end of the base frame, and a C-shaped hook at the chain exit end engageable with a side edge of the base frame. The shoe is engaged with the base by first engaging the C-shaped hook with the side edge of the base frame, then flexing the chain entry end of the shoe until the hook at the chain entry end can receive the chain entry end of the base. The shoe is moved a short distance toward the chain exit end of the base until a projection formed on a back surface of the shoe near the chain entry end snaps into a depression formed on a front surface of the base frame, locking the shoe and base together.
