A cover is provided for a pipe coupling (1) wherein the cover has a first part (2) in the form of an impervious collection chamber adapted to cover approximately one circumferential half of a pipe coupling. The collection chamber is defined by a pair of spaced generally parallel flexible side walls (3, 41) and a peripheral wall (4) that preferably includes a transparent zone interconnecting corresponding radially outer edges of the side walls to form the collection chamber. Free edges of the walls that form an opening communicating with the collection chamber have deep generally semi circular recesses (5) for accommodating one half of the circumference of a pipe (6) adjacent a coupling in use. A co-operant second part (9) of the cover serves as a retainer for the first part, in use. The second part has similar side walls (11) and at least one interconnecting peripheral wall (12) with recesses in free edges of the side walls for accommodating an opposite half of the circumference of a pipe adjacent a coupling in use. Each of the recesses has a lateral collar (7, 13, 33, 40) extending around its periphery. Means are provided for holding the collars around the outer surface of a pipe in use. |
