Be it known that we have invented a new, original, and ornamental design for a guide member for a lace tightening device, of which the following is a specification, reference being made to the accompanying drawings, forming a part thereof. Description of the Figures: Fig. 1.1is a perspective view of the guide member for a lace tightening device; Fig. 1.2is a top view of the guide member for a lace tightening device; Fig. 1.3is a bottom view of the guide member for a lace tightening device; Fig. 1.4is a first side view of the guide member for a lace tightening device; Fig. 1.5is a second side view of the guide member for a lace tightening device; Fig. 1.6is a front view of the guide member for a lace tightening device; Fig. 1.7is a back view of the guide member for a lace tightening device. The guide member is attachable to an article, such as an article of footwear, and is configured to guide or direct a lace; the lace can be tensioned, via a lace tightening device, to close or tighten the article, such as tightening an article of footwear about a wearer's foot; the portions illustrated by solid lines are the portions for which the claimed design is intended; the broken lines in the drawings represent environment that form no part of the claim.
