At its outer end, clip 2 has a transverse endmember 5, which has the shape of a split cylinder, which has separated transverse edges Ea. Said clip 2 has longitudinal and planar legs L, which are parallel to each other and parallel to the straight longitudinal axis of helical spring 6.

Said legs L have outer end- portions 4a and 3a which are transversely tapered, so that their wide edges are integral with edges 5a of endmember 5. Said legs L have main body- portions 4 and 3 which are rectangular.

The inner ends of said legs L have integral flangeiwhich interfits slidably andziturnablyiwith' 1949,1'Setia'iFNdi91480 2 T lateral'e'xtensions '8 and l which'i ext'en'd in opposed lateral directions.

40 Ir;it heextensions 8 andc'ltareipreferablyoriginally formed or shaped relative to legs L, prior to forming or shaping the end-flanges 8 and I. When thus originally formed or shaped, each lateral extension 8 and I has surplus material for subsequently forming the end-flanges 8a. and 1a.

When lateral extensions 8 and 1 are shaped prior to forming the end-flanges 8a and 1a, said junction lines E preferably follow the desired helical contour. When the surplus material is then bent inwardly along junction lines E, to form end-flanges 8a and 1a, each said end-flange 8a and la has the desired part-helical shape.

As shown in Fig. 3, the lateral extensions 8 and 1 are diametrically laterally opposed, so that 3 their end-flanges 8a and 1a are also diametrically opposed.

Each end-flange 8a and la turnably and slidably engages substantially one-fourth of the circumference of a coil of helical spring 6.

In using this specific embodiment, the endfianges 8a and 1a are engaged with one end of spring 6. The cross-bar I is extended through the hollow end-member 5. The clip 2 is turned relative to spring 6, until cross-bar I is clamped between end-member 5 and the respective end of spring 6.

As shown in Fig. 2, the thickness of inner endwalls 8b and lb is preferably greater than the normal longitudinal spacing of the coils of spring 6. Hence, when clip 2 is assembled with spring 6, said spring 5 is extended at inner end-walls 8b and lb and each inner end-wall 8b and 1b is clamped and frictionally held between two adjacent coils of spring 6.

The spring 6 may also thus frictionally clamp the lateral extensions 8 and 1.

Each junction line E has the shape of a part of a helix which has the same pitch as sprin 6, so that each junction line E has the same con;- tour as the coils of spring 6.

I have disclosed a preferred embodiment of my invention, but numerous changes and omissions and additions can be made without departing from its scope. sq

I claim:

1. A holding device, said device comprising a clip which has legs which are spaced from each other, said legs being connected to each other at the end of said clip, a helical spring assembled with said clip,'each of said legs extending within the interior of. said spring and having a first lateral offset which is located between adjacent first and. second turns of said spring and which frictionally engages said respective adjacent turns of said spring and which has substantially the same pitch as said spring, each of said first lateral offsets having an extension which is external to said spring and which is substantially parallel to the axis of said spring and which has substantially the same pitch as said spring and which has an inner convex wall which is adapted slidably to receive said second turn of said spring and which is directed away from the end of said clip, each of said extensions having a second lateral offset which is located between said second turn of said spring and an adjacent third turn of said pring and which frictionally engages said second and third turns of said spring and which has substantially the same pitch as said spring.

2. A holding device, said device comprising a clip which has legs spaced from each other and connected to each other at the end of said clip, a helical spring assembled with said clip, the legs of said clip extending partially within the central hollow interior of said helical spring, said legs having respective lateral offsets which project in diametrically opposite directions, between adjacent turns of said spring, said lateral offsets having sufiicient thickness to be frictionally engaged and compressed between the respective adjacent turns of said spring, each of said lateral offsets having an arcuate end extension located exteriorly of said spring and embracing a portion of the outer periphery of one of the adjacent spring turns, the free end of each said extension extending between said embraced spring turn and the next adjacent turn and being compressed therebetween, said extensions having substantially the same pitch as said spring and being slidable around the outer periphery of said spring, whereby said legs may be moved longitudinally through the interior of said spring when said clip is rotated relative to said spring.

3. A holding device, said device comprising a clip which has legs spaced from each other and connected to each other at the end of said clip, a helical spring assembled with said clip, the legs of said clip being connected at one end and being free at their other end, said legs extending within the central hollow interior of said helical spring and being axially aligned with said spring, each of said legs having a terminal lateral ofiset, said offsets extending substantially perpendicularly of said legs in opposite directions and between adjacent turns of said spring, said offsets having suflicient thickness to be compressed between the respective adjacent turns of said spring, each of said ofisets having an arcuate end extension located exteriorly of said spring and embracing a portion of the outer periphery of one of the respective adjacent spring turns, the free ends of each said extension extending between said embraced spring turn and the next adjacent turn and being compressed therebetween, said extensions having substantially the same pitch as said spring and being slidable around the outer periphery of said spring, whereby said legs may be moved axially through the interior of said spring when said clip is rotated relative to said spring.
