31) and a protruding retaining member (14;34) adjacent said pointed end arranged to interlock with the receiving part (20), and wherein said receiving part (20) is substantially u-shaped with at least one transversal base (25) and at a position at a distance from said transversal base (25) an interlocking receiving member (22) arranged to interlock with said penetrating part (10), wherein at least one of said parts (10, 20) is arranged with a gripping member (19, 29) which is detachable by means of a line of rupture (17, 27), and a method of fastening buttons. ## Claims ### Claim 1 A button fastener comprising: a penetrating part; a receiving part, wherein said penetrating part is substantially U-shaped by means of having a transversal base with two substantially parallel legs, each of said legs having a pointed end and a retaining member adjacent said pointed end arranged to interlock with said receiving part, and wherein said receiving part is substantially U-shaped with at least one transversal base and at a position at a distance from said transversal base an interlocking receiving means arranged to interlock with said penetrating part; and a detachable gripping member detachably connected to at least one of the transverse base of the penetrating part or to the receiving part by a breakable connection, wherein the gripping member is detachable by means of a line of rupture. ### Claim 2 (depends on 1) The button fastener according to claim 1, wherein said retaining member is protruding. ### Claim 3 (depends on 2) The button fastener according to claim 2, wherein said transversal base of the receiving part is arranged with said detachable gripping member. ### Claim 4 (depends on 2) A button fastener according to claim 2, wherein said protruding retaining member together with a body portion comprising each respective pointed end form barb like portions. ### Claim 5 (depends on 4) A button fastener according to claim 4, wherein said barb like portions are symmetrically positioned in relation to a centre line of the U-shaped part. ### Claim 6 (depends on 5) A button fastener according to claim 5, wherein said protruding retaining members protrude in directions to face each other. ### Claim 7 (depends on 1) The button fastener according to claim 1, wherein said transversal base of said penetrating part is arranged with said detachable gripping member. ### Claim 8 (depends on 1) A button fastener according to claim 1, wherein said penetrating part and said receiving part are arranged as one single unit. ### Claim 9 (depends on 8) A button fastener according to claim 8, wherein said penetrating part and said receiving part are attached to each other by means of a releasable attachment. ### Claim 10 (depends on 9) A button fastener according to claim 9, wherein said releasable attachment is in the form of a line of rupture. ### Claim 11 (depends on 1) A button fastener according to claim 1, wherein at least one of said parts is made in plastic. ### Claim 12 (depends on 1) A button fastener according to claim 1, wherein both parts are made in plastic. ### Claim 13 A method for fastening a button comprising: providing a penetrating part and a receiving part, wherein said penetrating part is substantially U-shaped by means of having a transversal base with two substantially parallel legs, each of said legs having a pointed end and a retaining member adjacent said pointed end arranged to interlock with said receiving part, and wherein said receiving part is substantially U-shaped with at least one transversal base and at a position at a distance from said transversal base an interlocking receiving means arranged to interlock with said penetrating part; providing at least one of said parts with a detachable gripping portion detachably connected to at least one of the transverse base of the penetrating part or to the receiving part by a breakable connection, wherein the gripping portion is detachable by means of a line of rupture; bringing said pointed ends of said penetrating part through a material; positioning a button having holes onto said pointed ends of said penetrating part to allow said pointed ends and a part of the legs to penetrate into said holes of said button; utilizing said at least one gripping portion to interconnect said penetrating part and said receiving part thereby fastening said button; and detaching said gripping portion. ### Claim 14 (depends on 13) The method according to claim 13, wherein both parts are provided with gripping members. ### Claim 15 (depends on 13) The method according to claim 13, wherein said penetrating member and said receiving member are arranged to form a single unit prior to use. ### Claim 16 (depends on 13) The method according to claim 13, wherein said gripping member is provided in a size arranged to be grip able by a person. ### Claim 17 (depends on 13) The method according to claim 13, wherein said gripping member has a transversal extension that is bigger than the length of said transversal base. ### Claim 18 (depends on 13) The method according to claim 13, wherein said gripping member has a transversal extension that is between 2-10 times bigger than the length of said transversal base.
