A flexible pipe coupling is disclosed. This coupling comprises a large diameter cylindrical hollow body, a pair of small diameter cylindrical hollow bodies each having one end portion disposed inside each end of the large diameter cylindrical hollow body on the same axial line, and an elastic sleeve member for connecting each end of the large diameter cylindrical hollow body to one end of each of the small diameter cylindrical hollow bodies. The elastic sleeve member is provided at its both ends adjacent to the cylindrical hollow bodies with protrusions each extending outwardly in the widthwise direction of the sleeve member at a radius of curvature corresponding to 0.1.about.0.4 times the thickness of the sleeve member, whereby the durability of the coupling is further improved.

Flexible pipe coupling

A flexible pipe connector which makes use of a pair of intermediate sleeves each having one end portion overlapped with and connected through a rubber-like elastic body to a connection pipe, each of said intermediate sleeves being coaxially arranged with the connection pipe and adapted to move in a fluid-tight manner in the axial direction thereof.
