The annular seal 26 is provided with stripes 40a having radially outer points 42 which are pressed against the first cavity 30 to retain the annular seal 26 in the first cavity 30 when the pipe elements are separated. As a result, ommission or loss of the seal can be prevented when the pipe elements are separated.
