Abstract
An external cover pipe is adapted to be fixedly fitted over a fluid transport pipe made of synthetic resin via an elastic seal. The cover pipe includes a plurality of split pipe members divided in the peripheral direction of the pipe which cooperate to compress the elastic seal in association with a fastening operation of a fastener for fastening and joining together the split pipe members disposed adjacent each other in the peripheral direction. Each split pipe member includes, in an inner peripheral face thereof, a deformation limiting face for coming into contact with an outer peripheral face of the fluid transport pipe in association with the fastening operation of the fastener so as to limit radial deformation of the fluid transport pipe. This deformation limiting face is provided at a portion in the inner peripheral face of the split pipe member located at a position axially offset toward an extreme axial end of the external cover pipe away from a portion thereof where the elastic seal is attached.
