Abstract
A heat sink/retainer clip (54) capable of resiliently holding objects, such as printed circuit boards, in tubular members, such as telemetering tools. The heat sink/retainer clip comprises two portions (56, 60) which extend across the tube from opposite sides thereof and two portions (58, 62) which engage the inner periphery of a tube (48). The clip is made of a resilient material, and the outer radii of the second two portions is slightly greater than the inner radius of the tube, so that the clip is distorted by the tube, during assembly, to resiliently grip the object between the first two portions.
