A frictional coupling for a male member inserted in the bore of a female member, to couple together the two members when at a pre-determined axial position. The opposed surfaces of the male and female members define a clearance the radial dimension of which varies as the members are moved axially relative to one another. A frictional coupling element is provided in said clearance, which element comprises a strip of resilient material preformed to a polygonal shape such that the outer corners contact the bore of the female member and the inner flats contact the male member. As the clearance is reduced by relative axial movement of the members, the element is deformed to restrain further movement therebetween. |
