A portable hoop lock comprising:

• a lock body and a lock hoop,
• wherein the lock hoop can be selectively introduced into the lock body or at least partly detached from the lock body and wherein the lock body comprises an electromechanical locking mechanism that is configured to selectively lock the lock hoop introduced into the lock body against a detachment from the lock body or to release the lock hoop for the detachment from the lock body,
• wherein the electromechanical locking mechanism has an electric motor, at least one latch element drivable by the electric motor and an energy source for supplying the electric motor with electrical energy,
• wherein the energy source is arranged in a housing that has a replacement opening through which the energy source can be introduced into the housing and removed from the housing, and
• wherein the hoop lock has a cover that can be plugged onto the housing along a plug-on direction to close the replacement opening,
• wherein the housing has at least one sealing section that forms an elevated portion at a side wall of the housing,
• wherein the elevated portion extends peripherally around the sidewall, wherein the at least one sealing section is elastically deformable,
• wherein the at least one sealing section can be at least one of compressed between the cover and the housing or elastically deformed along the plug-on direction by plugging on the cover onto the housing for sealing the replacement opening;
• wherein the at least one sealing section is arranged such that the energy source can be removed from the housing without removing the at least one sealing section from the housing.
