ABSTRACT:
A male end is inserted in a socket with radial clearance. An annular elastically yieldable sealing element has an outer heel portion disposed in an inner groove in the socket. A single lip portion on the sealing element extends inwardly of the socket and has a radially inner end which grips the male end. The heel portion has, at rest, an axial dimension which is of the same order of magnitude as its radial dimension and exceeds the axial dimension of the groove. The axial dimension of the groove is greater than the greatest radial space between the male end and the edge of the groove adjacent the entrance of the socket.
