ABSTRACT The invention relates to a clamping ring and closure means made of plastic material comprising a closure head integrally formed at one end of a clamping ring of U-shaped section and which has a passage into which the opposite end (in the form of a tongue) of the clamping ring, can be inserted. Interlocking saw or locking teeth are provided on the side edges of the tongue and on the side walls of the passage, and the side walls of the closure head are connected together by non-overlapping spacer webs which bound the passage on the upper side of the closure head and at the exterior of the base of the clamping ring. The sawteeth on the two side walls are in each case disposed opposite one another at the points of attachment of the spacer webs, and the saw or locking teeth on the tongue, extend outwardly at an acute angle in relation to the longitudinal axis of the clamping ring. The end surfaces of these teeth extend approximately perpendicularly to said longitudinal axis, and along one side edge of the tongue a reinforcing strip is formed which projects in the direction of the open section side of the clamping ring and whose inner side is provided with sawteeth. The locking teeth formed on this side edge are widened over the outer side of the latter so that the lower spacer webs lying at the exterior of the base of the clamping ring section have, in each case, a portion which lies at the extremities of the limbs of the U-section and which is offset in step form bounding a deeper portion of the passage corres- ponding to the reinforcing strip, a bent-over portion of the spacer webs having a sawtooth facing the deeper portion of the passage.
