ABSTRACT:
The horn comprises a body portion, a detachable and hence replaceable end portion, and a securing member securing the end portion to the body portion. The securing member has a first threaded portion received in a tapped hole in the body portion and a second threaded portion received in a tapped hole in the end portion. By rotation of the first threaded portion in its tapped hole, the orientation of the end portion, when it is in tight contact with the body portion, can be corrected. A method of detachably securing an end portion to a body portion of a horn is also claimed.
