Disclosed is a pinching clip which comprises a pair of pinching arms interconnected through the medium of a hinge portion, an elastic brace disposed astraddle said hinge portion and joined at the opposed extremities thereof with the rear sides of said pinching arms, and damping pieces disposed one behind each said pinching arm in such a way that when the two pinching arms are closed by virtue of the pressure exerted thereon by the finger tips, the otherwise possible sudden closing motion of the clip will be retarded. When the clip is closed, the damping pieces disposed on the rear sides of the pinching arms produce an action of retarding the movement of finger tips, with the result that otherwise possible sudden closing motion of the clip is retarded when the clip changes form from its opened state into its closed state.

Disclosed is a device for supporting electric wires, cords and other elongated bodies, which comprises a 'U'-shaped frame body having a catch provided on one free end of the frame body, a lid member hinge-connected to the other free end of the frame body and a spring member extending from the inner wall of the lid member. In use, a plurality of elongated bodies are laid on the spring member, and the lid member is pushed down until the free end of the lid member is caught by the catch of the 'U'-shaped main body, thus putting the elongated bodies in the rectangle space defined by the main body and the lid member. The spring member continuously applies a force to the lid member in its opening direction as a counter action resulting from the state in which the spring member is pushed against the bottom part of the main body and is yieldingly deformed. Thus, the lid member is positively assured from undesired opening and releasing the elongated bodies.

Disclosed is a plastic device for clampingly holding a length of electric cord which device comprises two 'L'-shaped halves hinge-connected to each other, each having an L-shaped groove. In use, a length of electric cord is curved in the form of an L, and is fitted in the groove of one half, and then the other half is rotated around the hinge-connection to overlie said half in which the cord has been fitted. The two grooves constitute a complete round hole in which the electric cord is contained in a clamped condition. With this arrangement the clamp holder according to this invention assures a positive grip of the electric cord against any 'pull-out' force applied to the electric cord.

Disclosed is a plastic sealing device comprising a hollow, bottomless cubic body and a sealing strip integrally connected to and extending from said cubic body. The sealing strip has an arrowhead-shaped end, and in use, the arrowhead-shaped end of the strip is inserted in the slits of the hollow cubic body, and is pulled out of the cubic body, thus passing therethrough and closing the open bottom of the cubic body. After passing through the apertures of an object to be sealed, the arrowhead of the strip is inserted in a slit in the top plate of the cubic body until it is caught by catch means within the cubic body. The structure of the sealing device is conveniently amenable to plastic injection moulding and mass-production.

A process for forming a collapsable tube having a flexible inner tube and a resilient outer tube. A shoulder member is formed having connecting surfaces. A flexible inner tube is joined to the shoulder member at a connecting surface. An outer tube encompassing the inner tube is joined to the shoulder member at a separate connecting surface so that the outer tube overlaps the joint between the inner tube and shoulder member. To resist permeation, the inner tube is formed by lap welding a laminated sheet of different natured materials and depositing a molten material along an edge of the sheet to seal it.

Disclosed is a screw grommet which is used to bolt an object to a plate or the like. The unique structure of a screw grommet according to this invention permits frictionless insertion of the leg of the grommet in an aperture of the plate and at the same time, positive engagement with the circumferential edge of the aperture of the plate.
