A chain guide (10) secured to an attachment tab (22) of an attachment link (20) of a roller chain (12) is disclosed for stabilizing the roller chain (12) on a chain rail (14). Chain guide (10) is generally symetrical about longitudinal and lateral axes and includes a central, right parallelepiped portion (26) integrally formed intermediate end portions (34) having a cross section of an isosceles triangle. The surfaces (36) of end portions (34) pilot chain guide (10) onto the chain rail (14). The support surfaces (28) of portion (26) slideably abut the face (16) of the chain rail (14). A socket (46) is provided intermediate and parallel to the support surfaces (28) for slideably receiving the attachment link (20). In the most preferred form, chain guide (10) is secured to the attachment tab (22) by detents (56) formed on the sides (48) of socket (46) for a snap interlock with a hole (24) formed in the attachment tab (22).
