Abstract: The invention relates to a coupling for connecting and/or holding together two parts, in particular for a bicycle trailer, having a first and a second coupling part which cooperate and can be released from each other, one of which is an insert piece which is connected to one of the parts and the other is a sleeve which is connected to the other part, the sleeve being capable of at least partly engaging around the insert piece, and the first coupling part having at least one locking groove (22, 103). To achieve a constructively simple coupling with a simple handling ability, mounted on or in the second coupling part is at least one locking shaft (4, 96) which has at least one locking segment having in the peripheral direction at least one locking portion (31, 131) and one unlocking portion (32, 132), the locking portion (31, 131) having a greater radial extent than the unlocking portion (32, 132). The locking shaft (4, 96) is arranged so that the locking portion (31, 131) can engage in the locking groove (22, 103) when the insert piece has been introduced into the sleeve, and the unlocking portion (32, 132) cannot engage in the locking groove (22, 103). Furthermore, means are provided for rotating the locking portion (31, 131) into the locking position, for holding the locking portion (31, 131) in the locking position and for releasing the locking portion (31, 131) from the locking position.

Abstract translation: 本发明涉及一种用于连接和/或固定在一起的两个部件，特别是用于自行车拖车的联接器，该部件具有第一和第二联接部件，该第一和第二联接部件配合并且可以相互释放，其中一个部件是插入件， 连接到所述部件中的一个，而另一个是连接到另一部分的套筒，所述套筒能够至少部分地接合在所述插入件周围，并且所述第一联接部件具有至少一个锁定槽（22,103） 。 为了实现具有简单处理能力的建设性简单的联接，安装在第二联接部件上或其中的至少一个锁定轴（4,96）具有至少一个锁定部分，该锁定部分在周向方向上具有至少一个锁定部分（31 ，131）和一个解锁部分（32,132），所述锁定部分（31,131）具有比所述解锁部分（32,132）更大的径向延伸。 锁定轴（4,96）被布置成使得当插入件已经被引入套筒中时，锁定部分（31,131）可以接合在锁定槽（22,103）中，并且解锁部分（32,132） ）不能接合在锁定槽（22,103）中。 此外，提供用于将锁定部分（31,131）旋转到锁定位置的装置，用于将锁定部分（31,131）保持在锁定位置并且将锁定部分（31,131）从锁定位置释放。
