A sleeve (10, 10a-e) for protecting a utility conduit or conduits passing through a hole in a stud (12, 12a-b) used in building construction. A provided body portion (16) forms a longitudinally extending hollow trough. The trough includes a circular side section (24), with a diameter defining a body width (30). This circular side section is changeable by compression with either the human hand or a conventional hand-tool to adapt the body width, and thus the sleeve, to coincide with a potential range of stud hole sizes. Engagement of the sleeve in the hole can be achieved by placing an inserted end (32) into the hole and pressing a worked end (34). A provided stop portion (18) at the worked end then stops insertion of the sleeve beyond the stud face, and a provided retention portion (20) in the sleeve affirmatively retains the sleeve within the hole once it is thus inserted.
