s claims. (crei-Lise) y pensive to construct, easy to operate and which presents g a pleasing appearance.

Another object is to provide a fastening device which will"ti'ghtly grip a cord or tape.

Still another object is to provide a fastening device in which the gripping parts are guided for uniformly gripping two portions of cord or tape to form a loop therein.

A further object is to provide a fastening device in which the parts are held against accidental disassembly.

The above and other objects and advantages of the invention will be more readily apparent from the following description when read in connection with the accompanying drawings, in which- Figure 1 is a perspective view of a fastening device embodying the invention with tape gripped therein;

Figure 2 is an enlarged central section through the fastening device; and

Figure 3 is an end elevation.

The fastening device as shown is adapted to grip a cord or tape indicated generally at I at spaced points in the length thereof to form a loop whose size may easily be adjusted. The device as shown is adapted to be used variably to tighten the sleeves or necks of garments to close bags such as laundry bags and the like and for similar related uses. It will be understood that the cord employed may be of circular or flat section in the form of usual twisted string or of a woven ribbon or tape and the term cord, as used herein, is intended to cover all such forms of materials.

The fastening device itself includes a base member formed with a generally at flanged portion II having a central conical projection I2 thereon. The flat ilanged portion II has openings I3 formed therein at opposite sides of the projection I2 so that the cord can extend through the openings and lie against the sides of the projection. In the form shown, the openings I3 are elongated arcuate slots to receive a nat tape, but it will be seen that their shape can be varied as desired to accommodate different sizes and shapes of cords.

The fastening device is completed by a cover member I4 having a conical recess I5 formed therein of a size and shape to fit over the projection I2. VAt its outer end the cover member is' .formed with openingsl adjacent the sides of thefrersessr I5fv through whichfthe cord may extendas "shown in Figure 2. With thisconstruction it will b e seen that when the basey and cover members vare pressed ,t'of'getherg` a cord extending through the openings willbe gripped between the sidesofftleprojfection and the recess to vhold the cord tightly inplace against movement in the fastening device. In order to insure uniform gripping of the two portions of the cord and to prevent wedging of the cover and the base parts which might interfere with their operation, guide means are provided to guide the base and cover members for straight line movement. As shown, the guide means comprise a pin I'I rigidly secured to the cover member I4 coaxial with the recess I5. The pin I'I slidably ts in a bore formed in the projection I2 so that the cover and base members will be guided thereby for straight line movement parallel to the axis of the projection and the recess. This construction insures equal gripping of the two portions of the cord and prevents the base and cover members from jamming against each other so that they cannot be operated easily.

The outer end of the pin I'I is enlarged as indicated at I9 and fits into an enlarged opening 2| communicating with the bore I 8 and connected thereto by a stop shoulder22. Upon separation of the base and cover members, the enlarged head I 9 will engage the stop shoulder 2'2 to prevent complete separation of the members and to insure that they will always be held in proper relationship.

The base and cover members as described may be lformed of any desired material such as metal, molded plastics or the like. If desired, a finishing cover 23 may be attached over the base member,` as shown, to present a pleasing appearance and a similar cover 24 may be attached over the outer end of the -cover member. For many uses these covers may be omitted, although they may be easily attached when desired for decoration.

While only one embodiment of the invention has been shown and described in detail herein, it is to be understood that it is illustrative only and is not to be taken as a definition of the scope of the invention, reference being had for this purpose to the appended claims.

What is claimed is:

l. A fastening device for a cord or the like comprising a. base member having a central tapered projection and formed with openings therethrough adjacent the sides of the projection through which a cord may extend, a cover member formed with a tapered recess to fit over the projection and squeeze the cord against it and having openings therethrough opening into the recess through which the cord may extend, one of the members being formed with a bore coaxial with the projection and recess, and a guide pin carried by the other member slidably tting in the bore to guidethe members for centered straight'line"mcvement `relative to each other'.

2. A fastening device for a cord or the like comprising a base member having a substantially flat anged portion and a central conical projection, the flanged portion being formed'wi'th a pair of openings at opposite sides of thefprojection through which the cord may extend, a cover member formed with a cen-trai?ccriial'ecess to t over the projection and having apair of y openings therethrough communicating With the recess through which the cord may extend, .and one 'oftf the' members being .formed with a"A bore coaxial with the projection and the recess",4 and a guide pin onlthe otherim'ernber"slidably tting inthe bore. j

y '3. 'fastening device fora -cord or thelke' 'comprising abase "member havingl a substantially" flat hangedA portion? and a" central conical projection, the flanged portion-being' fcrm'edwithat pair of openings at opposite sides of the projection through which the cord may extend, a cover member formed with a central conical recess to fit over the projection and having a pair of openings therethrough communicating with the recess through which the cord may extend, and one of the members being formed with a bore coaxial with the projection and the recess, and terminating'in an enlarged portionconn'ected tothe bore 'by a st'op `shoulder, and "afg-uide" pin slidable in the bore and having an enlarged end tting in the 'i enlarged portion to engage the stop shoulder and prevent separation of the members.
