9 Claims.

formed from a single piece of sheet metal and which may be mounted in snap fastener engagement with an apertured support.

Illustrative of the invention, reference is made to the accompanying drawing showing a preferred embodiment of the invention, and in which Fig. 1 is a top plan view of a strand or wire retainer according to the invention;

Fig. 2 is an edge elevation illustrating the retainer mounted on a support;

Fig. 3 is a side elevation of the retainer per se:

Fig. 4 is an edge elevation thereof; and

Figs. 5 and 6 are views similar to Fig. 2 illustrating alternative modes of grouping a plurality of conductors in the retainer,

Referring to the illustrated embodiment shown in the drawing, the invention comprises a retainer formed with opposed channel-shaped receiving portions separated by a central web, which is provided with integral snap fastener means for attaching the retainer to an apertured support, the web having an elastic band or strap secured thereto for embracing a plurality of strands under tension.

Referring more particularly to the drawing, the retainer may advantageously be formed of a single strip of sheet metal, the opposite end portions of which are shaped to channel form, as at l0, presenting a web II and upper and base flanges l2 and I3, respectively. The two channel-shaped portions l0 are preferably connected together by an intermediate strip ll of less width so that the lower flanges I3 may be disposed on opposite sides of the strip M. The strip M is bent on itself to provide a nose portion i5 with sides connecting the nose and web portions II, said sides having diver-gent portions l6 and convergent portions l1 presenting an outward bow or bulge l8 spaced below the flanges II.

The intermediate or connecting portion thus formed provides a snap fastener means for readily attaching the retainer to a support I which is formed with an aperture 2. As will be apparent from Fig. 2, the nose protion l5 provides a ready means for forcing the snap fastener portion through the aperture of the support, and, when the retainer is in its fully afilxed position, the opposite faces of the support I are engaged by the base flanges l3 and bowed portions l8. Preferably the lower flanges I3 are downwardly inclined as shown, so that the ends or feet perifs tions thereof engage the adjacent surface of the support in planes spaced beyond the bowed portions l8, thus providing a tensional gripping effeet between the ends and bowed portions.

An elastic strap or band 20 is suitably connected to one of the web portions II and preferably the web portions H are formed with elongated slots 22 through which. an end of the band 20 may be inserted. The other end of the band may be formed with a stop 2| formed in any suitable way, as by a thickened part of the band 20, to prevent the band from being pulled entirely through the slots 22.

The end portions of the upper flanges may be formed with suitable fastening means for the band, and conveniently these fastening means 23 may be in the form of opensided or T-slots into which an intermediate part of the stretched band, 20 may be hooked.

In use, the retainer is snapped into position on an aperturecl support, as above described, and the elastic band 20 is drawn through the slot 22 until the stop 2! engages the opposite webs H. A group of strands, such as electrical conductors.

; may be assembled in one of the channels HI and the elastic band thus stretched and extended around the group of strands to engage them under tension. An intermediate portion of the band may be hooked in each of the T-slots, as shown in Figs. 2 and 6, or may be passed around the end of the upper flange I 2 of the receiving channel and hooked into the opposite slot 23, as shown in Fig. 6.

The upper flanges l2 may be upwardly sloping so as to present a valley in which an additional group of conductors may be retained as shown in Fig. 6.

The invention provides an efllcient retainer of extremely simple construction which will effectively hold one or more separated groups of strands in secure position. It will be clear that the strap is reversible in the web portions H so that a group of strands may be positioned in either channel HI.

While I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope of my invention is best defined by the following claims.

I claim:

1. A strand-retainer comprising opposed channel-shaped strand-receiving portions having an intermediate web, fastener means formed as a continuation of the web and extending below said channel-receiving portion, an elastic strap secured at one end to said web, said retainer having a strap-receiving opening in another part thereof, said strap being stretchable to embrace a plurality of strands grouped in one of said channels to hold said strands in place, and an a ring a strap-receiving opening in another part thereof, said strap being stretchable to embrace a plurality of strands grouped in one of said channels to hold said strands in place, and an intermediate portion Of the strap being hooked into said strap-receiving opening.

3. A strand-retainer comprising opposed channel-shaped strand-receiving portions, each having upper and lower flanges and an intermediate web portion, snap fastener means formed as a continuation of the web and extending below said i channel-receiving portion, each of said web portions being formed with an elongated slot, an elastic strap extending through said slots, and at least one of the upper flanges having a strapreceiving opening, said strap being stretchable to embrace a plurality of strands grouped in one of said channels and holding said strands in place, and an intermediate portion of said strap being hooked into said strap-receiving opening.

4.
