Electronic handheld device with a housing having at least one housing element, an electronic arrangement (3, 4) and a battery compartment arranged in the housing element for accommodating a flat battery for supplying electrical voltage to the electronic arrangement (3, 4), wherein the battery compartment terminates at an access surface of the housing element with an insertion opening of the battery compartment for removing or inserting the flat battery for a battery change, wherein a circumferential sealing groove is formed on the access surface of the housing element, which groove completely surrounds the insert opening once, wherein the insertion opening is openably and resealably closed by a sealing capot arranged on the housing element for sealing the battery compartment against an entry of liquid into the battery compartment, wherein the sealing capot has an elastically deformable sealing projection on a sealing surface facing the access surface, wherein the seal projection is formed complementary to the seal groove and is introduced within the seal groove, wherein the seal projection has an oversize in a radial direction of the seal groove relative to the seal groove such that the seal projection is elastically deformed within the seal groove by the seal groove in the radial direction to bring about a sealing effect by restoring forces brought about as a result of the seal projection's radial elastic deformation in the seal groove, wherein the housing comprises a side decorative element connected to the housing element, characterised in that the sealing capot has a clamping tab with a retaining opening, wherein the clamping tab is arranged in abutment against a side surface of the housing element and with the retaining opening engaging around a retaining projection between the housing element and the side decorative element and in abutment against both. wherein the battery compartment terminates at an access surface of the housing element with an insertion opening of the battery compartment for removing or inserting the flat battery for a battery change, wherein a circumferential sealing groove is formed on the access surface of the housing element, which groove completely surrounds the insert opening once, wherein the insertion opening is openably and resealably closed by a sealing capot arranged on the housing element for sealing the battery compartment against an entry of liquid into the battery compartment, wherein the sealing capot has an elastically deformable sealing projection on a sealing surface facing the access surface, wherein the seal projection is formed complementary to the seal groove and is introduced within the seal groove, wherein the seal projection has an oversize in a radial direction of the seal groove relative to the seal groove such that the seal projection is elastically deformed within the seal groove by the seal groove in the radial direction to bring about a sealing effect by restoring forces brought about as a result of the seal projection's radial elastic deformation in the seal groove, wherein the housing comprises a side decorative element connected to the housing element, characterised in that the sealing capot has a clamping tab with a retaining opening, wherein the clamping tab is arranged in abutment against a side surface of the housing element and with the retaining opening engaging around a retaining projection between the housing element and the side decorative element and in abutment against both.
