<p>A protective device 10 of hollow sleeve-like construction comprises a body portion 12 of cylindrical form, and a head portion 14 of hollow ogival form truncated to form an aperture 16. The device is formed of a resilient plastics material and split down one side so that it may be contracted to be push-fitted into a number of fishing pole sections of smaller diameter. A shoulder 18 of depth less than the typical wall thickness of a fishing pole is defined between the head portion and the body portion. The depth of the shoulder portion remains substantially constant irrespective of the diameter of the body and head portions.</p> |
