The inner sleeve has a recess which is intended to receive a forward part of a javelin tip. The outer sleeve has a tubular axially trailing part, the inner diameter of which is such as to obtain an elastic, squeeze fit around a rear part of the javelin tip. The outer sleeve has an internal recess which accommodates the inner sleeve. Similar to the forward end of the inner sleeve, the forward end of the outer sleeve is also of externally, frontally hemispherical shape. The inner sleeve is located in the axially leading part of the outer sleeve.
