ABSTRACT:
A separable device for connecting tubular elements, hoses, rods or the like, comprising a tubular housing and a clamping member. In such a connecting device, a passage is formed in the tubular housing and comprises at least near one end a portion which is enlarged in diameter and which conically tapers toward the exit cross-section of the passage. The clamping member consists of a tubular member, which has an inside diameter that corresponds to the outside diameter of the tubular member, hose, rod or the like, and an outside diameter that corresponds to the diameter of the exit cross-section of the tubular housing. The tubular clamping member is adapted to be inserted into the tubular housing and into the enlarged portion to be retained therein by an enlarged end rim consisting of an annular bead, the outside diameter of which is smaller than the inside diameter of the enlarged portion but larger than the exit cross-section of the passage. The end portion of the clamping member which is provided with the enlarged rim is provided with a plurality of longitudinal slots, which extend through the shell and define resilient tongues in the tubular clamping member.
